Designed for the plastics industry, the hopper magnet protects molding machinery and other processing equipment from damaging ferrous metal. Separation can be conveniently monitored through the transparent drawer face. Slide gate shuts off product flow and is provided as a standard feature. An easy clean design is available. Hopper magnets remove small particles of ferrous metal from free flowing powders and granular materials. These permanent magnetic separators are a very cost efficient way to remove damaging tramp metal and light concentrations of ferrous contaminants from chemicals, pharmaceuticals, cosmetics, plastics, food, grain, fertilizer sand, clay and minerals.
