Mpi grate magnets are designed to remove medium and small-size ferrous tramp metal contaminants from dry, granular free-flowing product streams in gravity-fed vertical chutes, hoppers, housings, or bins. They are easy to install and clean. Magnetic grates offer efficient, economical magnetic protection of processing equipment, such as milling, extruding, and mixing, while improving product purity. With these types of magnetic separators, the product stream flows through a row of 1in diameter magnetic tubes, located on 2in centers, allowing 1in of space between each tube. The tubes are held in place with a welded stainless-steel support frame. As tramp metal contaminants are captured, they move to the underside of the magnetic tubes, eliminating tramp metal inwash-offin. All tubes are fully welded for the highest durability, no crimped or mechanically sealed end plugs. All mpi grate magnets are proudly manufactured in the usa.
