Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron (NdFeB), which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface has a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium cylindrical and flat pot magnets have an operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic strength. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

Important to know

Loss of holding force

To prevent loss of holding force due to magnetic short-circuit, neodymium magnets with a brass shell may not be pressed directly into iron. Always maintain a certain distance between the brass shell of the pot magnet and the iron. Contact Goudsmit for specific recommendations.

Permanent bullet magnets have a powerful bullet-shaped ferrite magnet core. They are suitable for filtering medium to large ferrous contaminants from high capacity coarse free-fall bulk flows.Often used in eg. the bulk, animal feed, plastics, ceramics and recycling industries. 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

Stop the product flow
Loosen the fastener clamps
Put on sturdy work gloves
Open the door as far as possible
Wipe clean the magnet core while turning it around its axle
Catch the removed ferrous particles and dicharge them
Re-tighten the fastener clamps
Restart the product flow

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron (NdFeB), which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface has a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium cylindrical and flat pot magnets have an operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic strength. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

Important to know

Loss of holding force

To prevent loss of holding force due to magnetic short-circuit, neodymium magnets with a brass shell may not be pressed directly into iron. Always maintain a certain distance between the brass shell of the pot magnet and the iron. Contact Goudsmit for specific recommendations.

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

Stop the product flow
Loosen the fastener clamps
Put on sturdy work gloves
Open the door as far as possible
Wipe clean the magnet core while turning it around its axle
Catch the removed ferrous particles and dicharge them
Re-tighten the fastener clamps
Restart the product flow

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron (NdFeB), which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface has a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium pot magnets have an operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic strength. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

Important to know

Loss of holding force

To prevent loss of holding force due to magnetic short-circuit, neodymium magnets with a brass shell may not be pressed directly into iron. Always maintain a certain distance between the brass shell of the pot magnet and the iron. Contact Goudsmit for specific recommendations.

Construction of ferrite pot magnets

Good magnetic properties, affordably priced

Ferrite pot magnets, also referred to as ceramic pot magnets, are fitted with a steel pot that provides shielding of the magnetic field. Ferrite pot magnets require only a minimal installation height. This provides constructive advantages.

Operating temperature

When does loss of magnetic strength occur?

Ferrite pot magnets have an operating temperature of up to 200 °C. When heated to this temperature, the magnet loses 30 to 40% of its magnetic force. This is not permanent; the force is restored when the magnet temperature returns to the normal ambient temperature. The magnet force of these pot magnets is lower than that of neodymium pot magnets.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

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

Stop the product flow
Loosen the fastener clamps
Put on sturdy work gloves
Open the door as far as possible
Wipe clean the magnet core while turning it around its axle
Catch the removed ferrous particles and dicharge them
Re-tighten the fastener clamps
Restart the product flow

Compact magnet systems with a steel shell and a countersunk hole for easy mounting. The bolt with a flat countersunk head falls flush with or in the top of the magnet. This optimizes the attracting surface of the pot magnet. Thanks to the shell of these magnet systems, the magnetic field strength increases and the pot magnets are more resistant to corrosion or chemicals. Pot magnets have a single attracting surface. This precludes dispersion of the magnetic field.Pot magnets with countersunk hole are available in various sizes and types such as neodymium, ferrite and AlNiCo.

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron - (NdFeB) - which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface is covered with a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium pot magnets have a maximum operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic force. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.
 

Important to know

Tension on the magnet

For pot magnets with a cylinder hole, the magnet has a countersunk hole. Tighten with caution. Excessive tightening causes magnetic splinters or cracks in the magnet.

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

Stop the product flow
Loosen the fastener clamps
Put on sturdy work gloves
Open the door as far as possible
Wipe clean the magnet core while turning it around its axle
Catch the removed ferrous particles and dicharge them
Re-tighten the fastener clamps
Restart the product flow
