Application

Sweeping floors to clean them from iron particles

Magnetic brooms (magnetic sweepers) 'sweep up' iron particles from clean or rough floors or sandy surfaces. They work well in areas where it is very difficult to sweep up iron (or just the iron and nothing else) or it is not visible, such as in sand.
 
The strong magnet in the broom collects metal debris, such as nails, screws, nuts, chips and grinding dust in workshops, factory halls, festival areas, exhibition halls and on paved or sandy parking lots or camping grounds.

Types

We have standard types and 'specials' available

In addition to the standard magnetic brooms on this page, we are happy to make a special broom for you on request. Other dimensions or attachments for forklift forks or trailers, etc.

Cleaning (iron disposal)

Cleaning & discharging of caught iron particles

Bar magnet type
The bar magnet has a scraper ring, with which you can slide the captured iron particles to the side. There the iron automatically falls from the bar housing.
 
Plate magnet type
This type of magnetic broom contains a strong plate magnet with a hinged separator plate (extractor plate) in front. After the floor has been swept the separation plate can be swung away, causing the iron particles to automatically fall off. It can then easily be swept up with a dustpan and broom.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

 
Goudsmit has plenty of experience with this and will be happy to provide recommendations.

Design

Design

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit. These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions. Various versions available to meet your needs:

Belt width: 400-2000 mm
Diameters: 150-400 mm
Magnet system: both axial and radial magnet construction


Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.

Application

Application

Plate magnets / magnetic plates are cost-effective, robust magnets. They are suitable for filtering metal parts from free-fall product flows or products on a conveyor belt with relatively little Fe contamination. Permanent plate magnets can be easily built into existing installations. In this way they protect processing machines reliably and economically, which prevents downtime of production processes. The effectiveness of plate magnets varies from 70 to 90% iron depletion. If an even cleaner product is desired, several magnets or magnet systems can be used in succession.

Placement

Placement

Overbelt placement or installation in/against a free-fall line. For placement in a free-fall line Goudsmit also supplies mounting plates (see also chute magnets). This makes dust-proof mounting possible and makes them easy to clean.
 
For a width in excess of 300 mm a neodymium magnet is recommended for installation in a free-fall line. In such applications ferrite plate magnets are too heavy for manual cleaning. If you are considering overbelt placement, keep in mind that the construction directly beneath the magnet must be made of non-magnetic material.

Design

Design

Goudsmit builds plate magnets for mounting above production lines that feature 'flux control' to create a deeper holding field. These have extra magnets between the poles that cause the lines of flux to penetrate deeper into the product flow. A ridge prevents captured iron particles from being carried away again by the product flow.

Cleaning

Cleaning

Cleaning of the plate magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning). Hereby you swing the extractor plate away from the magnet. The Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field. For quick cleaning, see also chute magnets.

Application

Application

Ferrite magnetic plates (plate magnets) remove ferromagnetic (Fe) particles as small as 0.5 mm. An advantage is that they are suitable for use at higher temperatures (250°C), but they are not suitable for capturing stainless steel scrapings.
 
The dimensions are selected based on the desired holding field depth: the deeper the field, the heavier and larger the magnet becomes. For this reason one often opts for the more compact and equally strong neodymium (Neoflux®) plate magnets.

Placement

Placement

Overbelt placement or installation in/against a free-fall line. For placement in a free-fall line Goudsmit also supplies mounting plates (see also chute magnets). This makes dust-proof mounting possible and makes them easy to clean.
 
For a width in excess of 300 mm a neodymium magnet is recommended for installation in a free-fall line. In such applications ferrite plate magnets are too heavy for manual cleaning.

Application

Cleaning unit application

In order to easily clean the magnet unit and to ensure operator safety, Goudsmit has developed the magnet rotor cleaning unit. It is available as an accessory with the rotating Cleanflow magnet. With this cleaning unit, the magnetic bars are easily removed from the extractor and securely placed on the tray. This keeps the magnet clean, preventing it from falling on the ground or being attracted by a steel object. The magnet is then easily accessible from all sides and therefore easy to clean. Even if the magnet unit is saturated with attracted metal particles, and the magnetic bars are therefore very difficult to remove from the extractor, this is not a problem with the cleaning unit. The tray collects the attracted iron parts.

Application

Application

Permanent ferrite suspended magnets (block magnets) consume no energy, which is one of the factors that makes them so price effective. These magnets remove ferromagnetic (Fe) particles as small as 0.5 mm (depending on the layer thickness on the belt).

Cleaning

Cleaning

Cleaning of the block magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning), by swinging the extractor plate away from the magnet; the Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field. Hereby you swing the extractor plate away from the magnet. The Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field.

Placement

Placement

A block magnet is hung above a conveyor belt, by means of chains or cables. The addition of these magnets can considerably boost separation yield:
 
Placement over pulley: In this configuration the magnet hangs at an angle over the end of the conveyor belt, where discharge of the material occurs. This is the ideal situation, because the bulk flow is ‘broken open’ at this point. When this happens, the iron particles are exposed within the surrounding material. This allows them to be more easily drawn to the magnet. Keep in mind, however, that it is important for the construction directly beneath the magnet to be made of non-magnetic material; otherwise it, too, will become magnetized.
 
Placement over band: This position is used for small layer thickness (or mono-layers). Or when there is no other option due to the potential for magnetization of underlying steel components (such as motors or guide rollers).

Working principle

Working principle

Suspended magnets (block magnets) remove undesirable ferromagnetic (Fe) particles such as iron and steel from material flows containing relatively little Fe contamination. They are placed above flat or trough-shaped conveyor belts. The metal particles are drawn out of the raw material flow and held by the magnet. This results in a pure iron fraction suitable for immediate reuse (recycling).
 
They are used to check incoming product flows and for the protection of machines, such as shredders and sieves. When heavy metal contamination is present, it is better to use an overbelt magnet; this type continuously carries away the iron particles.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.

Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Application

Application

Ferrite magnetic plates (plate magnets) remove ferromagnetic (Fe) particles as small as 0.5 mm. An advantage is that they are suitable for use at higher temperatures (250°C), but they are not suitable for capturing stainless steel scrapings.
 
The dimensions are selected based on the desired holding field depth: the deeper the field, the heavier and larger the magnet becomes. For this reason one often opts for the more compact and equally strong neodymium (Neoflux®) plate magnets.

Placement

Placement

Overbelt placement or installation in/against a free-fall line. For placement in a free-fall line Goudsmit also supplies mounting plates (see also chute magnets). This makes dust-proof mounting possible and makes them easy to clean.
 
For a width in excess of 300 mm a neodymium magnet is recommended for installation in a free-fall line. In such applications ferrite plate magnets are too heavy for manual cleaning. If you are considering overbelt placement, keep in mind that the construction directly beneath the magnet must be made of non-magnetic material.

Design

Design

Goudsmit builds plate magnets for mounting above production lines that feature 'flux control' to create a deeper holding field. These have extra magnets between the poles that cause the lines of flux to penetrate deeper into the product flow. A ridge prevents captured iron particles from being carried away again by the product flow.


Cleaning

Cleaning

Cleaning of the plate magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning). Hereby you swing the extractor plate away from the magnet. The Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field. For quick cleaning, see also chute magnets.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

 
Goudsmit has plenty of experience with this and will be happy to provide recommendations.

Design

Design

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit. These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions. Various versions available to meet your needs:

Belt width: 400-2000 mm
Diameters: 150-400 mm
Magnet system: both axial and radial magnet construction


Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.

Application

Application

Plate magnets / magnetic plates are cost-effective, robust magnets. They are suitable for filtering metal parts from free-fall product flows or products on a conveyor belt with relatively little Fe contamination. Permanent plate magnets can be easily built into existing installations. In this way they protect processing machines reliably and economically, which prevents downtime of production processes. The effectiveness of plate magnets varies from 70 to 90% iron depletion. If an even cleaner product is desired, several magnets or magnet systems can be used in succession.

Working principle

Filtering & discharging of ferrous contaminants

Cleaning of the plate magnet is performed manually by wiping, or through use of a hinged extractor plate for quick-cleaning. You can swing the hinged extractor plate away from the magnet. The ferrous particles fall off of the extractor plate as soon as they are moved far enough away from the magnet.
 
For plate magnets including mounting plate and hinged cleaning construction: see also 'chute magnets'.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit. These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions.

Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.

Application

In pouring points, hoppers, as inspection before bagging, etc.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.

Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Application

Application

Ferrite magnetic plates (plate magnets) remove ferromagnetic (Fe) particles as small as 0.5 mm. An advantage is that they are suitable for use at higher temperatures (250°C), but they are not suitable for capturing stainless steel scrapings.
 
The dimensions are selected based on the desired holding field depth: the deeper the field, the heavier and larger the magnet becomes. For this reason one often opts for the more compact and equally strong neodymium (Neoflux®) plate magnets.

Placement

Placement

Overbelt placement or installation in/against a free-fall line. For placement in a free-fall line Goudsmit also supplies mounting plates (see also chute magnets). This makes dust-proof mounting possible and makes them easy to clean.
 
For a width in excess of 300 mm a neodymium magnet is recommended for installation in a free-fall line. In such applications ferrite plate magnets are too heavy for manual cleaning. If you are considering overbelt placement, keep in mind that the construction directly beneath the magnet must be made of non-magnetic material.

Design

Design

Goudsmit builds plate magnets for mounting above production lines that feature 'flux control' to create a deeper holding field. These have extra magnets between the poles that cause the lines of flux to penetrate deeper into the product flow. A ridge prevents captured iron particles from being carried away again by the product flow.


Cleaning

Cleaning

Cleaning of the plate magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning). Hereby you swing the extractor plate away from the magnet. The Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field. For quick cleaning, see also chute magnets.

Operation

Operation

Gauss meter measurements use the Hall effect as the measuring principle. The sensor captures the magnetic flux density that is perpendicular to the sensor plane. The magnetic field generates an output voltage on the sensor, which is proportional to the product of the magnetic field strength and the induced current.


1D gauss meter

Type HG09: Basic version - 1D gauss meter

For measurement on a surface. The basic version is a one-dimensional meter (1D) equipped with a single Hall sensor which measures the flux density in one direction.   Suitable for: accurately measuring flux densities in one direction with a large range (max. 4.5 T) both static and alternating fields and pulses thanks to a thin measuring probe, measurements very close to the surface and in crevices measurements of fields where the local field orientation is known. This gauss meter is used to measure peak flux density of permanent and electromagnetic systems for inspections.


3D gauss meter

Type 3 Axis VGM: 3D gauss meter

The 3D meter allows you to measure magnetic fields in a free space. This gauss meter is equipped with three Hall sensors, which measure the flux density in three directions (x, y and z).   Suitable for: measuring relatively low flux densities in three directions and the ensuing results - up to max. 80 mT; scanning magnetic fields with a set alarm level. Application examples: determining safe distances in connection with exposure to static magnetic fields (medical implants, projectile hazards, pregnant workers); measuring residual magnetism in products, for example before and after demagnetizing; determining local field orientation of magnetic fields.

Small ferrous contaminants / lightweight / food

Neodymium magnetic plates are extremely powerful, compact and lightweight. They are used when ferromagnetic (Fe) particles smaller than 3 mm must be separated. Completely stainless steel and watertight. Suitable for the food industry.
 
You can easily hang them suspended above a conveyor belt yourself, attach them to the wall of a product channel, or mount them under a passing product stream. For dust-tight installation against the wall of a free-fall pipe channel, we also supply neodymium plate magnets including a mounting plate and quick-cleaning mechanism (see chute magnets).
 
If the product comes in direct contact with the magnet, we recommend type 3; this has an extremely high field strength at the magnet yet a compact field, which also makes it ideal for capturing weakly magnetic particles, such as stainless steel scrapings. Type 2 was developed for overbelt placement or installation in a free-fall line with mounting plate.
 
* Note: If you are considering overbelt placement, keep in mind that the construction directly beneath the magnet must be made of non-magnetic material.

Working principle

Filtering & discharging of ferrous contaminants

Cleaning of the plate magnet is performed manually by wiping, or through use of a hinged extractor plate for quick-cleaning. You can swing the hinged extractor plate away from the magnet. The ferrous particles fall off of the extractor plate as soon as they are moved far enough away from the magnet.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit.

Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.

Application

Cleaning unit application

In order to easily clean the magnet unit and to ensure operator safety, Goudsmit has developed the magnet rotor cleaning unit. It is available as an accessory with the rotating Cleanflow magnet. With this cleaning unit, the magnetic bars are easily removed from the extractor and securely placed on the tray. This keeps the magnet clean, preventing it from falling on the ground or being attracted by a steel object. The magnet is then easily accessible from all sides and therefore easy to clean. Even if the magnet unit is saturated with attracted metal particles, and the magnetic bars are therefore very difficult to remove from the extractor, this is not a problem with the cleaning unit. The tray collects the attracted iron parts.

Application

In pouring points, hoppers, as inspection before bagging, etc.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.

Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Application

Application

Permanent ferrite suspended magnets (block magnets) consume no energy, which is one of the factors that makes them so price effective. These magnets remove ferromagnetic (Fe) particles as small as 0.5 mm (depending on the layer thickness on the belt).

Cleaning

Cleaning

Cleaning of the block magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning), by swinging the extractor plate away from the magnet; the Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field. Hereby you swing the extractor plate away from the magnet. The Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnetic field.

Placement

Placement

A block magnet is hung above a conveyor belt, by means of chains or cables. The addition of these magnets can considerably boost separation yield:
 
Placement over pulley: In this configuration the magnet hangs at an angle over the end of the conveyor belt, where discharge of the material occurs. This is the ideal situation, because the bulk flow is ‘broken open’ at this point. When this happens, the iron particles are exposed within the surrounding material. This allows them to be more easily drawn to the magnet. Keep in mind, however, that it is important for the construction directly beneath the magnet to be made of non-magnetic material; otherwise it, too, will become magnetized.
 
Placement over band: This position is used for small layer thickness (or mono-layers). Or when there is no other option due to the potential for magnetization of underlying steel components (such as motors or guide rollers).

Working principle

Working principle

Suspended magnets (block magnets) remove undesirable ferromagnetic (Fe) particles such as iron and steel from material flows containing relatively little Fe contamination. They are placed above flat or trough-shaped conveyor belts. The metal particles are drawn out of the raw material flow and held by the magnet. This results in a pure iron fraction suitable for immediate reuse (recycling).
 
They are used to check incoming product flows and for the protection of machines, such as shredders and sieves. When heavy metal contamination is present, it is better to use an overbelt magnet; this type continuously carries away the iron particles.

Application

In pouring points, hoppers, as inspection before bagging, etc.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.
 

Magnet quality: neodymium N-42, Br 13,300 gauss (at 20 °C), Tmax. 80 °C. (8,000 gauss on tube Ø25)
Materials - in contact with product: AISI304 (RVS 1.4301) / AISI316 (SS 1.4401)


Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit. These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions. Various versions available to meet your needs:

Belt width: 400-2000 mm
Diameters: 150-400 mm
Magnet system: both axial and radial magnet construction


Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.
