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

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.

Add-on magnetic drum separators purify product streams. This takes place before the next processing step, such as non-ferrous separation or plastic sorting.
 
The undesired, weakly magnetic iron parts are then separated from the main current so that they do not interfere in the next machining step. This way you achieve a higher separation efficiency, which also results in the recovery (recycling) of a clean, salable iron fraction.
 
To achieve good separation it is important that the material is supplied in a consistent flow, which can be achieved with a vibratory feeder or conveyor belt for example.

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.

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.

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

Add-on magnetic drum separators purify product streams. This takes place before the next processing step, such as non-ferrous separation or plastic sorting.
 
The undesired, weakly magnetic iron parts are then separated from the main current so that they do not interfere in the next machining step. This way you achieve a higher separation efficiency, which also results in the recovery (recycling) of a clean, salable iron fraction.
 
To achieve good separation it is important that the material is supplied in a consistent flow, which can be achieved with a vibratory feeder or conveyor belt for example.

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)

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.

In case of overfed drum magnets, the material is fed over the drum. As soon as an iron part passes through the magnet, it is attracted and carried over the drum until the part comes out of the magnetic field. The iron part is then released and falls behind a divider plate.

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

Add-on magnetic drum separators purify product streams. This takes place before the next processing step, such as non-ferrous separation or plastic sorting.
 
The undesired, weakly magnetic iron parts are then separated from the main current so that they do not interfere in the next machining step. This way you achieve a higher separation efficiency, which also results in the recovery (recycling) of a clean, salable iron fraction.
 
To achieve good separation it is important that the material is supplied in a consistent flow, which can be achieved with a vibratory feeder or conveyor belt for example.

The magnet segment consists entirely of neodymium magnets.

The 8,000 gauss ('High gradient') drum magnet has a radial magnet system and is used for smaller layer thickness than the 6,000 gauss drum magnet. The 8,000 gauss is not really intended for separation of ferromagnetic particles. These may only be present sporadically, because they disrupt the magnetic field, which is detrimental to the separation of weakly magnetic metal particles. Therefore a 8,000 gauss drum magnet is usually placed at the end of a processing step (preceded by other separators).

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

Electro holding magnets can be used as:

Door magnets
Holding magnets are an essential component of a door magnet system. With the correct electromagnet, you build a secure system for automatically opening, closing or locking doors.
 
Pick & place magnet
Round electro holding magnets have a shallow magnetic field. This makes them particularly suitable for picking up, holding and unloading thin steel objects, up to 10 mm thick.
 
A known problem when picking up thin sheets with a powerful electro holding magnet is a too deep magnetic field radiation which causes the system to pick up several sheets at once. The use of many small electromagnets prevents this.
The maximum shear force is approximately 1/4 of the maximum holding force.
 
The central threaded hole on the back makes assembly very simple.

Working principle

Switchable with electric voltage

There are 2 types:
Electromagnet type attracts a steel object upon switching on the coil in the magnet. When the coil is switched off, the magnet immediately releases.
 
Electro-permanent magnet type possesses permanent magnet force. When the coil is turned off, the magnet pulls the workpiece. Switching on the coil neutralizes the permanent magnetic force. The magnet is now out of operation and immediately releases the workpiece.
 
These magnets are an ideal solution when you need to reliably hold the workpiece in the unpowered state.

Switching/power supply

Control of electro holding magnets

For the electrical switching and power supply of the magnets, a control cabinet is needed. These can be found in the accessories tab of the product variants.

Operation

Ferrite sheet separator operation

The magnetic field automatically forces the sheets apart and separates them. When the upper sheet is removed, the next one rises immediately.
To prevent malfunctions in fully automated production processes we recommend the use of a number of extra sheet separators.

Installation example 1

Corner installation

For optimum results, it is best to place two sheet separators at the corner(s) of stacks of large steel sheets.
The arrows in the photo indicate the recommended direction of transport in which the sheets can best be carried off after separation.

Installation example 2

Installation across from each other

Sheet separators placed across from each other ensure that the sheets begin to ‘float’.
The arrows in the photo indicate the recommended direction of transport in which the sheets can best be carried off after separation.

Installation example 3

Single-piece installation

For small sheets, it is best to place the sheet separator in the middle of the shortest side.

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.

With magnetic grippers, you automatically pick up flat steel products or sheets up to 10 mm thick. They are quick and easy to switch, and specially designed for transferring, placing or positioning using a robotic arm.Magnetic grippers serve as end of arm tooling for sheets. They even hold perforated sheets effortlessly.

Permanent magnet

Application

End of arm tooling

Magnetic grippers are ideal when you want to pick up, place or position flat, steel products with a robot. The applications are very diverse, such as:

pick-and-place of steel parts
handling perforated sheets with a robot arm
unstacking workpieces from crates (bin picking)
positioning sheets in presses
stacking or unstacking hot baking tins

The high temperature gripper is suitable for this last example. For example, you can also use it to load and unload high-grade steel in a press; it is formed at high temperatures.


Operation

Switching and control of the magnet gripper

The magnet gripper switches pneumatically. This moves the magnetic field and switches it on and off.
Control can be with a 5/3 or possibly a 5/2 valve.
An activated magnet gripper does not release its load, even if the air pressure or power supply is lost. This makes it a safe and reliable end-of-arm solution.

Practical tips

Things to look out for when using magnetic grippers:
When working with thin sheets (≤1 mm) you must consider the ‘peeling off effect’. This reduces the maximum breakaway force. In this situation, it is better to create a construction with multiple smaller grippers (e.g. 40 x 40 mm) than one or two large grippers.
A sheet can be damaged when the gripper contacts the sheet. If this is a problem, choose the version with a protective polyurethane cap (friction type).
When working with oiled sheets or with high acceleration of the robotic arm, a sheet can shift position. This, too, can be prevented through use of the type with a polyurethane friction pad.
Sometimes the surface of a sheet is not flat, so the vacuum does not work. In this case, magnetic grippers are an ideal solution. The more contact surface area the better, but a magnet gripper always works on ferromagnetic steel. Thus on round shapes too.
The vacuum does not work when there are holes in the sheet; the magnet gripper does. In this case, choose a gripper with larger dimensions than the hole, and test the chosen solution thoroughly.
For small workpieces, Goudsmit has very small grippers in the assortment. They have a low overall height and give extra strength to hold the workpiece in place. For example, choose type HGR-RO-020.
For thin sheets (≤4 mm) and oily sheets that stick together, the robot sometimes picks up several sheets together. Sheet separators prevent this. They are available both in permanent and pneumatically switchable versions.

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.

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.

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.

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

Add-on magnetic drum separators purify product streams. This takes place before the next processing step, such as non-ferrous separation or plastic sorting.
 
The undesired, weakly magnetic iron parts are then separated from the main current so that they do not interfere in the next machining step. This way you achieve a higher separation efficiency, which also results in the recovery (recycling) of a clean, salable iron fraction.
 
To achieve good separation it is important that the material is supplied in a consistent flow, which can be achieved with a vibratory feeder or conveyor belt for example.

The magnet segment consists entirely of neodymium magnets.

Type H
The 8,000 gauss ('High gradient') drum magnet has a radial magnet system and is used for smaller layer thickness than the 6,000 gauss drum magnet. The 8,000 gauss is not really intended for separation of ferromagnetic particles. These may only be present sporadically, because they disrupt the magnetic field, which is detrimental to the separation of weakly magnetic metal particles. Therefore a 8,000 gauss drum magnet is usually placed at the end of a processing step (preceded by other separators).

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)

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.

Operation

Operation of neodymium sheet separators

The magnetic field automatically forces the sheets apart and separates them. When the upper sheet is removed, the next one rises immediately.
To prevent malfunctions in fully automated production processes we recommend the use of a number of extra sheet separators.

Installation example 1

Corner installation

For optimum results, it is best to place two sheet separators at the corner(s) of stacks of large steel sheets.
The arrows in the photo indicate the recommended direction of transport in which the sheets can best be carried off after separation.

Installation example 2

Installation across from each other

Sheet separators placed across from each other ensure that the sheets begin to ‘float’.
The arrows in the photo indicate the recommended direction of transport in which the sheets can best be carried off after separation.

Installation example 3

Single-piece installation

For small sheets, it is best to place the sheet separator in the middle of the shortest side.
The arrows in the photo indicate the recommended direction of transport in which the sheets can best be carried off after separation.

Application

Application

Add-on magnetic drum separators purify product streams. This takes place before the next processing step, such as non-ferrous separation or plastic sorting.
 
The undesired, weakly magnetic iron parts are then separated from the main current so that they do not interfere in the next machining step. This way you achieve a higher separation efficiency, which also results in the recovery (recycling) of a clean, salable iron fraction.
 
To achieve good separation it is important that the material is supplied in a consistent flow, which can be achieved with a vibratory feeder or conveyor belt for example.

The 6,000 gauss (Power) drum magnet also has an axial magnetic system, but thanks to its high magnetic force and deep holding field it is also suitable for separation of coarse and even fine Fe particles and weakly magnetic particles such as stainless steel and other steel alloys. The magnet segment consists entirely of neodymium magnets.

Type H
The 8,000 gauss ('High gradient') drum magnet has a radial magnet system and is used for smaller layer thickness than the 6,000 gauss drum magnet. The 8,000 gauss is not really intended for separation of ferromagnetic particles. These may only be present sporadically, because they disrupt the magnetic field, which is detrimental to the separation of weakly magnetic metal particles. Therefore a 8,000 gauss drum magnet is usually placed at the end of a processing step (preceded by other separators).

Working principle

Working principle

In case of overfed drum magnets, the material is fed over the drum. As soon as an iron part passes through the magnet, it is attracted and carried over the drum until the part comes out of the magnetic field. The iron part is then released and falls behind a divider plate.

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.
