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.
