Grill magnetic separators

Grill magnetic separators

The grill magnet, also called magnetic grates or magnetic grids, is one kind of physical magnetic separators. As a professional magnetic manufacturers, our magnet factory design and produce different kind of silo-type permanent magnetic filter, . The grill magnetic separators is designed to make the dry, free-falling materials evenly distribute to surface of the magnetic filter system, and effectively sort magnetic objects passing through the cross section of pipes, chutes or silos. Unlike Eriez magnet and Bunting magnetics, all the magnets used in our mag filter and magnetic separator machine are from China, the biggest magnet producer in the world.

The permanent magnetic grate can be designed into various shapes, such as square, round, oval or fits the shape of the rounded hopper. It can also be made into single layer, double layer or multi-layer according to the processing accuracy requirements. The magnetic grids can be designed into an easy-to-clean magnetic frame as well. Through separating the sleeve and the magnetic system can achieve the purpose of quickly cleaning up iron impurities in powder or granular materials.

Characteristics and advantages

  • Integral stainless steel
  • The peak strength on surface of the magnetic rod is 14000 Gauss
  • Rare earth magnetic circuit design, extreme heat resistance up to 338°F
  • Surface material 316L cold drawn seamless tube
  • Can be used in the most rigorous sanitary environment

Optional configuration

  • A variety of field strengths and temperature tolerance criteria are available
  • The shape, size and layer numbers of the magnetic grid can be customized according to requirements
  • Diverter bars are available to enhance the iron removal effect.
  • Easy to clean (ETC) structure is more convenient for clean iron impurity
  • Sanitary-grade full welding or non-sanitary-grade spot welding can be optional
  • Magnetic grill can be equipped with corresponding cleaning device


Always applying for dry free-falling powder or granular in silos, irregularly shaped hoppers, closed chutes and other slopes and vertical pipelines to removal iron.
