Plate magnetic separator SPM


Plate magnetic separator SPM

Magnetic plate separator (SPM)

The SPM type plate magnetic separator is designed to remove iron contaminants from bulk materials (granulation up to 20 mm) in free fall systems. The plate separator protects process machines against damage caused by metal contamination, prevents production downtime and ensures product quality. The SPM separator also protects the consumer against eating dangerous metal pieces and is a perfect complement to a metal detector.

The SPM plate magnet is reliable, very robust and designed for continuous operation. The SPM separator is characterized by high metal separation efficiency. The ferrite or neodymium permanent magnets used in the magnetic plates have high coercivity, which makes them difficult to demagnetize. Therefore, the plate separator has a long service life.

Versions of the plate magnetic separator

  • SPM-F type plate magnetic separator
    Equipped with ferrite magnetic plates with medium magnetic field intensity designed to remove larger metal contaminants from the transported material, such as screws, bolts and other broken machine parts.
  • SPM-N type plate magnetic separator
    Equipped with neodymium magnetic plates with high magnetic field intensity designed to remove small metal contaminants from the transported material, such as bearing balls, metal filings, iron oxides and others with a small adhesion surface to the magnet and weakly magnetically susceptible.

Working principle of the plate separator

The contaminated product passes through the separator inlet and hits a specially profiled bulkhead that evenly divides the product stream onto magnetic plates placed on opposite walls of the separator housing. Ferrous impurities are attracted by the magnetic plates and accumulate behind the pole pieces, while the purified product leaves the separator through the outlet. The separator is cleaned by releasing the quick-release fasteners and folding away the magnetic plates.

Why choose our magnetic plate separator?

Magnetic plate separators are produced in many variants, adapted to the industry, the processed raw material and working conditions. The high quality of workmanship and effectiveness of our solutions have gained recognition among customers around the world. In addition to the standard catalog offer, we specialize in the production of plate separators for individual orders, also according to: entrusted design documentation. The separator housing is a laser-welded body made of stainless or acid-resistant steel. In a special version, a mechanism has been developed for quick and safe opening and cleaning of magnetic plates installed in the separator.
