Separate ferrous and nonferrous material in your line. These pulleys are often used to keep metal scraps from contaminating production lines, or for sorting applications such as recycling. As material moves over the pulley, a magnet tugs ferrous pieces against the belt. Nonferrous material flows over the end of the conveyor, but ferrous pieces travel around the curve and under the conveyor. Once the belt moves past the pulley’s magnetic field, those pieces will fall. Install as either the head or tail pulley.
