Eriez Cartridge Magnets, also referred to as Bullet Magnets, easily and efficiently remove tramp iron from dry, free-flowing materials in vertical pipelines. They are available with Ferrite or Rare Earth magnetic elements to satisfy customers’ unique application needs. In operation, material entering the housing is distributed by a solid stainless cone and passes in close proximity to the magnetic cartridge. Ferrous contamination is attracted and held by the magnet, while the separated product continues past the magnet and out of the housing. Ferrous contaminants remain securely on the magnet until the operator removes the cartridge for cleaning. The magnets feature stainless steel construction and are designed for pressures up to 1.7 Bar/25 psi.
