Application

Application

An overbelt magnet is suitable for removal or separation of high volumes of iron or steel and hangs above a flat- or trough-shaped conveyor. This type of magnet is self-cleaning and continuously separates (ferromagnetic) Fe parts from material streams. The iron removal efficiency of overband magnets ranges from 70 to 90%. This depends on magnet design, product flow and placement. Automatic self-cleaning overband magnetic separators are suitable for both the recovery (recycling) of ferrous parts and the removal/elimination of impurities (iron contaminants).
These magnets are mainly suitable for coarser fractions with pieces larger than 10 mm. Thanks to the robust, reliable technology, these magnets have applications in many industries. Putting a permanent overbelt magnet in service requires nothing more than four suspension points, sufficient space and power to drive the conveyor belt.

Operation

Operation

Conveyor belt speed:
to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized. To achieve maximum separation, it is important to optimally match the size of the magnet block (main pole) and the belt speed. This means that with a narrow overband magnet the conveyor belt beneath it must run at lower capacity (m/s) than with a wider magnet at the same suspension height. The following formula provides an indication of the maximum conveyor belt speed:
 
Maximum conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)
 
Recommended conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)

Placement

Placement

The distance between a magnet and the conveyor belt must be as small as possible. The magnetic force decreases exponentially with increasing distance. There is, however, a minimum distance required so the rubber cleats safely remove all the ferrous parts from the material flow. There are two methods for use/placement of overband magnets: transverse and in-line. Goudsmit has a specific, optimum magnet configuration for both mounting options.
 
Transverse ('Cross')
In practice, transverse placement is most common, because it is easier to install in an existing line. An additional advantage is a ferrous discharge to the side, which from the logistical perspective is easier to process.
 
'In-line'
If you have the option to place your overband magnet in line with the conveyor belt, this is always preferred. The advantage of this is that the transported material ‘breaks open’ at the end of the belt (head roller) and is therefore suspended in mid-air for several milliseconds. As a result, the magnet can easily pull the ferrous metal out of the product flow.

Non magnetic zone

Non magnetic zone

When positioning the magnet, the construction below the magnet such as the frame, bearing rollers and end rollers must be made of non-magnetic material. This is because steel parts will become magnetized, which will adversely affect the separation performance of the overband magnet.

Select your magnet size on the desired holding field depth. The deeper the field should reach, the heavier and larger magnet you have to select. For this reason it can be wise to select the more compact and strong neodymium (Neoflux®) plate magnets.
 
Placement
You can easily hang them suspended over a conveyor belt, 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 pipeline, we supply neodymium plate magnets including a mounting plate and quick-cleaning mechanism (see chute magnets).
 
* When placing above a belt, make sure that the construction directly below the magnet consists of non-magnetic material.

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.

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.

For sheets up to 10 mm thick
Switching: pneumatic
For robot End-of-arm tooling
Lifting power: up to 45 kg
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

Application

An overbelt magnet is suitable for removal or separation of high volumes of iron or steel and hangs above a flat- or trough-shaped conveyor. This type of magnet is self-cleaning and continuously separates (ferromagnetic) Fe parts from material streams. The iron removal efficiency of overband magnets ranges from 70 to 90%. This depends on magnet design, product flow and placement. Automatic self-cleaning overband magnetic separators are suitable for both the recovery (recycling) of ferrous parts and the removal/elimination of impurities (iron contaminants).
These magnets are mainly suitable for coarser fractions with pieces larger than 10 mm. Thanks to the robust, reliable technology, these magnets have applications in many industries. Putting a permanent overbelt magnet in service requires nothing more than four suspension points, sufficient space and power to drive the conveyor belt.

Operation

Operation

Conveyor belt speed:
to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized. To achieve maximum separation, it is important to optimally match the size of the magnet block (main pole) and the belt speed. This means that with a narrow overband magnet the conveyor belt beneath it must run at lower capacity (m/s) than with a wider magnet at the same suspension height. The following formula provides an indication of the maximum conveyor belt speed:
 
Maximum conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)
 
Recommended conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)

Placement

Placement

The distance between a magnet and the conveyor belt must be as small as possible. The magnetic force decreases exponentially with increasing distance. There is, however, a minimum distance required so the rubber cleats safely remove all the ferrous parts from the material flow. There are two methods for use/placement of overband magnets: transverse and in-line. Goudsmit has a specific, optimum magnet configuration for both mounting options.
 
Transverse ('Cross')
In practice, transverse placement is most common, because it is easier to install in an existing line. An additional advantage is a ferrous discharge to the side, which from the logistical perspective is easier to process.
 
'In-line'
If you have the option to place your overband magnet in line with the conveyor belt, this is always preferred. The advantage of this is that the transported material ‘breaks open’ at the end of the belt (head roller) and is therefore suspended in mid-air for several milliseconds. As a result, the magnet can easily pull the ferrous metal out of the product flow.

Non magnetic zone

Non magnetic zone

When positioning the magnet, the construction below the magnet such as the frame, bearing rollers and end rollers must be made of non-magnetic material. This is because steel parts will become magnetized, which will adversely affect the separation performance of the overband magnet.

Electro holding magnets are used for picking up, positioning and holding steel items. The round shape and a threaded hole at the bottom make them ideal for building into existing systems.These magnets are switched on and off with an electrical voltage.

For picking up, positioning or holding products
Switching: electric
Easy to install
Lifting power: up to 170 kg
Electropermanent or electromagnet

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.

Design

Goudsmit inspection bars are strong neodymium (Neoflux®) magnetic bars with a handle and an enclosed stainless steel (extractor) tube. You can easily remove attracted Fe parts by pulling the tube from the magnetic bar. In this way, the Fe parts fall off automatically. Includes a sturdy storage case.


Application

Application

Magnetic inspection rods are used to check or verify whether a product flow is free of ferrous metal. Due to the very high magnetic force, very small iron or stainless steel particles can be captured.

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

An overbelt magnet is suitable for removal or separation of high volumes of iron or steel and hangs above a flat- or trough-shaped conveyor. This type of magnet is self-cleaning and continuously separates (ferromagnetic) Fe parts from material streams. The iron removal efficiency of overband magnets ranges from 70 to 90%. This depends on magnet design, product flow and placement. Automatic self-cleaning overband magnetic separators are suitable for both the recovery (recycling) of ferrous parts and the removal/elimination of impurities (iron contaminants).
These magnets are mainly suitable for coarser fractions with pieces larger than 10 mm. Thanks to the robust, reliable technology, these magnets have applications in many industries. Putting a permanent overbelt magnet in service requires nothing more than four suspension points, sufficient space and power to drive the conveyor belt.

Operation

Operation

Conveyor belt speed:
to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized. To achieve maximum separation, it is important to optimally match the size of the magnet block (main pole) and the belt speed. This means that with a narrow overband magnet the conveyor belt beneath it must run at lower capacity (m/s) than with a wider magnet at the same suspension height. The following formula provides an indication of the maximum conveyor belt speed:
 
Maximum conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)
 
Recommended conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)

Placement

Placement

The distance between a magnet and the conveyor belt must be as small as possible. The magnetic force decreases exponentially with increasing distance. There is, however, a minimum distance required so the rubber cleats safely remove all the ferrous parts from the material flow. There are two methods for use/placement of overband magnets: transverse and in-line. Goudsmit has a specific, optimum magnet configuration for both mounting options.
 
Transverse ('Cross')
In practice, transverse placement is most common, because it is easier to install in an existing line. An additional advantage is a ferrous discharge to the side, which from the logistical perspective is easier to process.
 
'In-line'
If you have the option to place your overband magnet in line with the conveyor belt, this is always preferred. The advantage of this is that the transported material ‘breaks open’ at the end of the belt (head roller) and is therefore suspended in mid-air for several milliseconds. As a result, the magnet can easily pull the ferrous metal out of the product flow.

Non magnetic zone

Non magnetic zone

When positioning the magnet, the construction below the magnet such as the frame, bearing rollers and end rollers must be made of non-magnetic material. This is because steel parts will become magnetized, which will adversely affect the separation performance of the overband magnet.

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

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

An overbelt magnet is suitable for removal or separation of high volumes of iron or steel and hangs above a flat- or trough-shaped conveyor. This type of magnet is self-cleaning and continuously separates (ferromagnetic) Fe parts from material streams. The iron removal efficiency of overband magnets ranges from 70 to 90%. This depends on magnet design, product flow and placement. Automatic self-cleaning overband magnetic separators are suitable for both the recovery (recycling) of ferrous parts and the removal/elimination of impurities (iron contaminants).
These magnets are mainly suitable for coarser fractions with pieces larger than 10 mm. Thanks to the robust, reliable technology, these magnets have applications in many industries. Putting a permanent overbelt magnet in service requires nothing more than four suspension points, sufficient space and power to drive the conveyor belt.

Operation

Operation

Conveyor belt speed:
to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized. To achieve maximum separation, it is important to optimally match the size of the magnet block (main pole) and the belt speed. This means that with a narrow overband magnet the conveyor belt beneath it must run at lower capacity (m/s) than with a wider magnet at the same suspension height. The following formula provides an indication of the maximum conveyor belt speed:
 
Maximum conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)
 
Recommended conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)

Placement

Placement

The distance between a magnet and the conveyor belt must be as small as possible. The magnetic force decreases exponentially with increasing distance. There is, however, a minimum distance required so the rubber cleats safely remove all the ferrous parts from the material flow. There are two methods for use/placement of overband magnets: transverse and in-line. Goudsmit has a specific, optimum magnet configuration for both mounting options.
 
Transverse ('Cross')
In practice, transverse placement is most common, because it is easier to install in an existing line. An additional advantage is a ferrous discharge to the side, which from the logistical perspective is easier to process.
 
'In-line'
If you have the option to place your overband magnet in line with the conveyor belt, this is always preferred. The advantage of this is that the transported material ‘breaks open’ at the end of the belt (head roller) and is therefore suspended in mid-air for several milliseconds. As a result, the magnet can easily pull the ferrous metal out of the product flow.

Non magnetic zone

Non magnetic zone

When positioning the magnet, the construction below the magnet such as the frame, bearing rollers and end rollers must be made of non-magnetic material. This is because steel parts will become magnetized, which will adversely affect the separation performance of the overband magnet.

Ferrous contaminants > 0.5 mm / heavy / non-food

Ferrite plate magnets are cost-effective, yet less powerfull and larger than neodymium plate magnets. They have the advantage that they can be used up to 100 °C. They remove ferrous contaminants from 0.5 mm. Not suitable for weakly magnetic stainless steel contamination.
 
Select your magnet size on the desired holding field depth. The deeper the field should reach, the heavier and larger magnet you have to select. For this reason it can be wise to select the more compact and strong neodymium (Neoflux®) plate magnets.
 
Placement
You can easily hang them suspended over a conveyor belt, 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 pipeline, we supply neodymium plate magnets including a mounting plate and quick-cleaning mechanism (see chute magnets).
 
* When placing above a belt, make sure that the construction directly below the magnet consists of non-magnetic material.

Cleaning

Cleaning

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.

Filtering & discharging of ferrous contaminants

How does the magnetic filtering work?
Because the magnetic core is located in the middle of the product stream, the bullet magnet has a very high separation yield. The round shape of the housing and the magnetic core (with a 60° top cone) ensures continuous flow and good distribution of the product stream. The product then passes three powerful magnetic fields, where guide strips redirect any product near the outer walls back toward the magnetic core.
 
The magnets attract passing ferrous particles. The captured particles stick to 1 of the 3 magnet poles, while the purified product flows further.
 
How does the cleaning / iron discharging work?
You have to remove the captured ferrous particles manually. After having stopped the product flow, you can open the door. Then turn the magnet around its own axis, while wiping the magnet clean.

Permanent bullet magnets have a lower installation height compared to electro bullet magnets. Yet, you have to clean them manually, where this is done automatically with the electro bullet magnets.

Working principle

Filtering & discharging of ferrous contaminants

How does the magnetic filtering work?
Because the magnetic core is located in the middle of the product stream, the bullet magnet has a very high separation yield. The round shape of the housing and the magnetic core (with a 60° top cone) ensures continuous flow and good distribution of the product stream. The product then passes three powerful magnetic fields, where guide strips redirect any product near the outer walls back toward the magnetic core.
 
The magnets attract passing ferrous particles. The captured particles stick to 1 of the 3 magnet poles, while the purified product flows further.
 
How does the cleaning / iron discharging work?
You have to remove the captured ferrous particles manually. After having stopped the product flow, you can open the door. Then turn the magnet around its own axis, while wiping the magnet clean.
 
Cleaning / iron discharging sequence

Application

Application

An overbelt magnet is suitable for removal or separation of high volumes of iron or steel and hangs above a flat- or trough-shaped conveyor. This type of magnet is self-cleaning and continuously separates (ferromagnetic) Fe parts from material streams. The iron removal efficiency of overband magnets ranges from 70 to 90%. This depends on magnet design, product flow and placement. Automatic self-cleaning overband magnetic separators are suitable for both the recovery (recycling) of ferrous parts and the removal/elimination of impurities (iron contaminants).
These magnets are mainly suitable for coarser fractions with pieces larger than 10 mm. Thanks to the robust, reliable technology, these magnets have applications in many industries. Putting a permanent overbelt magnet in service requires nothing more than four suspension points, sufficient space and power to drive the conveyor belt.

Operation

Operation

Conveyor belt speed:
to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized. To achieve maximum separation, it is important to optimally match the size of the magnet block (main pole) and the belt speed. This means that with a narrow overband magnet the conveyor belt beneath it must run at lower capacity (m/s) than with a wider magnet at the same suspension height. The following formula provides an indication of the maximum conveyor belt speed:
 
Maximum conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)
 
Recommended conveyor belt speed (b) = block magnet width (a) / 0.3 (sec.)

Placement

Placement

The distance between a magnet and the conveyor belt must be as small as possible. The magnetic force decreases exponentially with increasing distance. There is, however, a minimum distance required so the rubber cleats safely remove all the ferrous parts from the material flow. There are two methods for use/placement of overband magnets: transverse and in-line. Goudsmit has a specific, optimum magnet configuration for both mounting options.
 
Transverse ('Cross')
In practice, transverse placement is most common, because it is easier to install in an existing line. An additional advantage is a ferrous discharge to the side, which from the logistical perspective is easier to process.
 
'In-line'
If you have the option to place your overband magnet in line with the conveyor belt, this is always preferred. The advantage of this is that the transported material ‘breaks open’ at the end of the belt (head roller) and is therefore suspended in mid-air for several milliseconds. As a result, the magnet can easily pull the ferrous metal out of the product flow.

Non magnetic zone

Non magnetic zone

When positioning the magnet, the construction below the magnet such as the frame, bearing rollers and end rollers must be made of non-magnetic material. This is because steel parts will become magnetized, which will adversely affect the separation performance of the overband magnet.

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

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

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.

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.
