Magnetic separators for recycling

There are several basic types of magnetic separators used in recycling facilities. The first is a magnetic drive roller that uses strong magnets to separate metal materials from waste. Its construction includes a solid magnetic core around the entire circumference of the shell.

Another widespread type is the belt magnetic separator above the conveyor, which is effective in separating larger metal pieces. Its main component is a magnetic block that attracts metal impurities from the material moving on the conveyor belt. Subsequently, these impurities are removed outside the material flow.

The working principle of these separators lies in their ability to create strong magnetic fields that attract ferromagnetic materials. In this way, they make it possible to effectively separate metals from other materials in the waste.

Magnetic separators are used in various industries, from municipal waste processing to industrial waste recycling. In the municipal sector, they are often used to separate metal packaging and other recyclable materials. In industries, they are essential for removing metal impurities from raw materials and materials used in production.

Eddy-current separator is an innovative solution for efficient separation of non-ferromagnetic metals (e.g. aluminum and copper) from non-metallic materials such as plastic, paper, wood or glass.

The principle of operation consists in the combination of an induction magnetic cylinder in which strong neodymium magnets are installed and a conveyor in which the magnetic cylinder is placed. High cylinder revolutions induce eddy currents. These currents temporarily charge the non-magnetic metals with the same magnetic charge as the induction coil. As a result, metals are repelled from the magnetic roller into the collection container, while non-metallic materials are naturally removed from the conveyor.

This induction magnetic separator offers unique separation options that classic magnetic separators cannot achieve. It can be used in various industries, such as recycling, waste disposal, electrical equipment or glass industry.
