The magnetic separator is composed of high-performance permanent magnetic core, scrap iron belt, reduction motor, frame, roller and other parts. It is used with various conveyors to automatically remove ferromagnetic substances from non-magnetic materials. The iron materials are separated from the raw materials by the magnetic separator. Rollers are installed at both ends of the magnetic separator. The rollers are sleeved with a conveyor belt. A high-strength magnet is placed in the middle of the belt, and the high-strength magnet is located in the middle of the two rollers. The material conveying belt is parallel below the magnetic separator, and its width is less than the length of the magnetic separator belt. The crushed mixed materials enter the conveyor belt from one end. When the iron blocks pass through the magnetic separator conveying belt, The magnetic material on the material conveying belt can be sucked out until the magnetism disappears when the conveyor belt on the magnetic separator rotates to the drum, and the magnetic metal falls due to its own neutrality, thus separating the general material from the magnetic metal, and the non-magnetic mixture continues to pass through the conveyor belt to achieve the iron removal during the material conveying process.
