Grate magnets are designed to remove ferrous metal and tramp iron from free-flowing materials such as plastics, foods, cosmetics, grains and minerals.
High-density permanent or rare earth magnetic tubes are arranged to draw iron particles onto the magnets and hold them there as material flows through the grate. Two styles of grate magnets are available in round or rectangular/square models to best suit your needs. Both are constructed of stainless steel with one-inch diameter magnetic tubes, normally arranged on 2” centers, but can be arranged for different spacing to provide the greatest magnetic efficiency. Optional Deflectors are added to deflect product flow, assuring material flows over the magnetic area.
An extension of the grate magnets are drawer grates. These grates are located directly over machinery openings and below material hoppers so that all material passes through the grate before entering the process machinery, insuring constant magnetic protection. These in-line magnetic filters are ruggedly constructed to support the weight of material hoppers, dryers and mixers. The magnetic housings match existing hopper mounting facilities for easy installation.
Magnetic Grate Assemblies are easily installed into existing rectangular or round duct systems for effective removal of tramp iron from free-flowing materials such as chemicals, grains and foodstuffs. These units are available in four bank models for fine iron separation and in two bank models for coarser tramp iron removal. Standard housing is of mild steel construction. Doors are hinged to allow easy removal, cleaning and replacement of the magnets. Individual drawers readily slide in and out on runners. Standard magnetic material is Alnico, Ceramic, or Rare Earth. Transition sections that adapt housing to duct work are optional, as is stainless steel construction.
Note: For greatest efficiency in tramp iron removal, the overall open area (space between tubes) should be approximately 10% greater than the cross sectional area of the duct.
