Bullet Magnet

Bullet Magnet

Bullet magnets can be used to filter undesired ferromagnetic (Fe) particles – such as iron and steel – out of granulates, fibres and coarser materials in high capacity free-fall lines or pneumatically conveyed products line.

Permanent bullet magnet is also called RF cartridge magnetic separator. Its cavity applys a neodymium iron boron (NdFeB) strong magnetic circuit design. When products enter the cavity of bullet magnet, they are spread out by the internal manget core, and the iron is absorbed on magnetic core surface at the same time, moreover the purified material continues to downward flow. When the door of bullet magnet is opened, permanent bullet magnets require manual cleaning during a production stop.

Characteristics and advantages

  • All stainless steel constructure
  • Standard design is suitable for high pressure pipeline
  • High strength "radial field " element
  • Stainless steel magnetic cone attached to dust-tight cover can be released easily by special clamps
  • Do't need to support the additional weight of access door when cleaning, reduce working strength
  • The magnet core is completely removable for easy clean

Optional configuration

  • Available in ceramic or rear earth magnet for tramp or fine iron removal
  • A variety of magnetic circuit and temperature tolerance criteria are available
  • The size and specification of inlet can be customized according to requirements
  • High pressure unites are available
  • Sanitary design is available


Powerful, radial-magnetic field bullet magnet removes tramp iron from dry, free-flowing materials in gravity or high pressure pneumatic conveying lines.

Material handling

Flour, starch, sugar powder, plastic particles, plastic resin, cocoa powder, starch, bread crumbs, etc.
