Drawer magnets effectively remove ferrous fragments and fines from free-flowing material. Housings are constructed 304 or 316L stainless steel. Strong magnetic grates inside filter the flow and extract the unwanted ferrous metal. They are widely used in food industry and chemical industry. Inside the housing, it can be one layer, two layers or more layers high intensity magnetic grates in frames. Cleaning of the magnets is easily accomplished by removing the tube casing of the grates and sliding out each magnet assembly.
