Manufacturer : Magnetic Products Inc.


MPI’s Automated Self-Cleaning 200 Series Drawer Magnets utilize a “Type A” magnetic circuit, which is ideally suited to capture small contaminants, such as wire, metal shavings and metal wear from dry powder or granular free-flowing product streams in gravity-fed vertical chutes. This Drawer Magnet protects processing equipment, such as milling extruding and mixing, while assuring high product quality standards with automatic magnet cleaning for maximum magnet performance.

MPI Automated Self-Clean Drawer Magnet

  • The product stream flows through a series of 1” diameter magnetic tubes designed to create an extremely effective magnetic circuit. Each row of magnetic tubes is staggered to
    prevent bridging or choking of the product stream and to maximize magnetic filtration as product flows through the housing. Tramp metal contaminants are attracted to the magnetic tubes. The pneumatically operated cleaning system safely removes tramp metal from the product stream to a disposal area outside the product flow area.
