Magnetic head pulleys are designed to remove the metallic contamination from the materials on the belt. They are positioned at the head of the belt conveyors. The rotating pulley holds the ferrous metal and allows the clean material to pass smoothly. The magnetism dissipates as the belt leaves the pulley, which led to the discharge of the unwanted contaminated materials. The contaminants are discharged into a separate receptacle. Magnetic Pulleys are best for removing metal which is buried in the product and has bypassed the magnetic field of other separation equipment.
