Fixed permanent sorting magnet (APRF)

In brief

• The fixed permanent sorting magnet (APRF) is installed at a fixed point in the process, generally above a conveyor, to retain ferromagnetic objects.

• It is used in recycling, mining, food processing and the production of construction materials.

• Unlike the overband magnet, it has no integrated self-cleaning system; it is mounted cross-belt or in-line at the conveyor discharge.

Fields of application

The fixed permanent sorting magnet is widely used in various industries where the separation of ferromagnetic materials is required:

• The recycling industry, to extract ferrous metals (steel, cast iron…) from mixed waste

• The mining sector, to purify ores and protect equipment from tramp metal parts

• The food processing industry, to remove small tramp metal particles from food products

• The production of construction materials, to ensure the purity of the end product

Operating principles

The fixed permanent sorting magnet operates on a simple yet effective principle:

• The permanent magnet is installed at a fixed point in the production process, generally above a conveyor.

• The strong magnetic field generated by the permanent magnet attracts the ferromagnetic objects present in the material flow.

• These ferromagnetic objects are retained by the magnet while non-magnetic products continue on their way.

• Unlike the overband magnet, this magnet has no integrated self-cleaning system.

Recommendations for use

To optimise the efficiency of a fixed permanent sorting magnet, here are some recommendations:

• Positioning & mounting: Choose a suitable mounting method, cross-belt or in-line at the conveyor discharge, at the point where the product flow is spread out as much as possible to maximise contact with the magnetic field.

• Regular cleaning: Set up a regular cleaning schedule to prevent saturation. Accumulated ferromagnetic parts would reduce the magnet’s efficiency if they are not removed.

• Safety: Make sure that the personnel responsible for cleaning are trained in safety procedures, as powerful magnets present risks.

• Adaptation to the flow: Adjust the height according to the product throughput to ensure that the magnetic field is sufficiently in contact with the ferromagnetic objects.

General characteristics

Fixed permanent sorting magnets have the following distinctive characteristics:

• Simplicity: Their simple design makes them reliable and easy to install, whatever the type of mounting (cross-belt or in-line at the conveyor discharge).
• Energy saving: As they require no power supply, they operate without any energy consumption
• Wide range: Available in several series (20, 25, 30, 35), covering belt widths from 650 mm to 1 800 mm, with weights ranging from 220 kg to 2 369 kg
• Durability: Manufactured from resistant materials, they are designed to last in demanding industrial environments
• Minimal maintenance: Apart from regular cleaning, they require no maintenance
• Available as an electromagnet version (RD)

Frequently asked questions

What is the APRF fixed permanent sorting magnet used for?

It separates ferromagnetic materials from a material flow and is generally installed above a conveyor. It is used in recycling, mining, food processing and the production of construction materials.

Does the APRF magnet need a power supply?

No, it requires no power supply and operates without any energy consumption. An electromagnet version (RD) is available for applications that require it.

What sizes and series are available for the APRF?

It is available in several series (20, 25, 30, 35), covering belt widths from 650 mm to 1 800 mm, with weights ranging from 220 kg to 2 369 kg.

How should the APRF magnet be cleaned and maintained?

It has no integrated self-cleaning system: regular cleaning is necessary to prevent saturation, as accumulated parts reduce its efficiency. Apart from this cleaning, it requires no maintenance, and personnel must be trained in safety procedures.

What mounting options are available for the APRF?

It can be mounted cross-belt or in-line at the conveyor discharge, at the point where the product flow is spread out as much as possible. The height should be adjusted according to the product throughput so that the magnetic field is properly in contact with the ferromagnetic objects.
