Magnetic Cylinders Separators with NdFeB Magnets

How to remove iron filings attached to a neodymium magnet (rod, separator)?

They can be easily removed by tapping them with adhesive tape. Another option is to blow them off with a compressor.

Maintenance and replacement interval

The stainless steel housing has a thickness of 1.5mm. It may become thinner due to the hardness of the magnetic substance and contact friction. Although the built-in magnets are permanent magnets, they have been embedded by applying resistive load. Therefore, even if the magnets are used within the specified heat resistance temperature, they may demagnetize over time due to repeated stress associated with fluctuations between hot and cold temperatures. There is no specific replacement period, but we recommend conducting regular tests for magnetic flux density and surface appearance.

What is the recommended distance between individual neodymium rod separators?

The distance between the rods is important during their arrangement. Adjust the processing speed according to your productivity based on the distance between the rods. The distance depends on the type of magnetic substance you want to process and the speed at which you operate.

How often is maintenance and replacement of magnetic inserts required?

The stainless steel housing has a thickness of 1.5mm, and it can be made thinner, but we do not recommend it due to rapid wear (abrasion). It may become thinner due to the hardness of the magnetic substance and contact friction. Although the built-in magnets are permanent (neodymium) magnets, they have been embedded by applying resistive load. Therefore, even if the magnets are used within the specified heat resistance temperature, they may demagnetize over time due to repeated stress associated with fluctuations between hot and cold temperatures. There is no specific replacement period, but we recommend conducting regular tests for magnetic flux density and surface appearance. 

Narrow spaces

This will be an accurate filter, and the processing speed for separating magnetic substances will be low.

Wide spaces

This will be a rougher filter, and the processing speed for separating magnetic substances will be higher.

• In such cases, the roughness of the filter and the processing speed can be improved by using more than 2 layers of magnetic filters.
• If there are multiple layers with narrow spaces between the rods, although the processing speed will be slower, the attraction capacity will increase.

Magnetic Separators (Rollers, Filters) are used to separate metals in food production and recycling.

Our magnetic rollers consist of neodymium magnets placed in a stainless steel housing. They are widely used for removing iron powder during the separation of metals from other waste materials in recycling, food production, and spinning. By using neodymium magnets as a magnetic separator, we prevent metal contaminants (iron scrap or fine iron powder, etc.) from getting into the food. M8 threaded holes are located on both ends, making it easy to mount them on machines (drawers). Choose the external housing, magnetic flux density on the surface, and heat resistance specifications that are suitable for your needs.

They capture even the smallest pieces of iron powder, shot, and needles.

They can be custom made to fit the required length, heat resistance, and pole spacing.

Upon individual request, we can produce rod magnets with millimeter tolerance (min. ±0.5mm).

• Heat resistance of 200°C (1 tesla, 10,000 gauss)
• Ultra high magnetism (1.4 tesla, 14,000 gauss)
• Very narrow pitch (thickness of 5mm, 10mm, mounted 15mm)
• Compatible with specifications of all types

We also accept orders for magnetic separators, products utilizing magnetic filters, and rod magnets in the shape of cubes.

For clients considering magnetic separators / magnetic filters but concerned about the installation process, we will provide explanations and assistance. Do not hesitate to ask us. We can also offer technical advice.

Procedure for producing magnetic shaft separators

Our magnetic separators are handmade by our skilled workers (we possess international welding certificates for methods 141, 142, 143, 145).
