Magnetic separator is to separate ferrous metal from wastes by permanent magnet which does not need the electrical power. The conveyor rotates around the large permanent magnet to separate steel wires, nails and gas cans moving on the conveyor. The body of the separator is of a non-magnetic structure made of steel. Which prevents ferrous items to be attracted to the body of the separator. In addition, the separator is designed in such a way that foreign materials are not stuck inside the conveyor belt to reduce abrasion of the belt, and to minimize maintenance.
