Continuous Flow Drawer Magnet


MPI’s Continuous Flow Self-Clean Drawer Magnets use a “type A” magnetic circuit to remove small to medium sized tramp metal from dry powder or granular free-flowing product streams in gravity-fed vertical chutes. These drawer magnets utilize four (4) tiers of magnets in two (2) doors, allowing for independent cleaning of each drawer without interrupting product flow. It protects milling, extruding and mixing equipment, while ensuring high product quality standards, 24 hours a day, seven days a week. These units are an excellent solution for applications which have high levels of tramp metal.

how it works
Product flows through a series of magnetic tubes designed to create an extremely effective magnetic circuit. Each row of magnetic tubes is staggered to prevent product bridging or choking and to maximize magnetic filtration. As tramp metal contaminant attaches to the magnetic tubes, the pneumatically controlled cylinders operate one double bank drawer of magnetic tubes at a time to safely remove the tramp metal from the product stream. As one drawer is in the cleaning position, the other is filtering the product stream, thus, allowing for the continuous flow of the product stream.
