Self-Cleaning Drawer Magnetic Separator will absorb and clean iron automatically, which is major for the material with much iron, clean the iron is convenient and quickly, the air cylinder pulls the magnetic rod layer by layer, the iron adsorbed on the magnetic rod automatically falls off, and the work is continuously, and the raw materials can continue to work when the iron is extracted one by one without stopping the feeding. The material is fed from the feed port of the magnetic separator and passes through the permanent magnet bar in the magnetic separator. The iron of the material is adsorbed on the magnetic bar by magnetic force, and the non-magnetic mineral particles pass through the magnetic bar and are discharged from the discharge port; At the same time, the permanent magnet bar is pulled layer by layer through the cylinder device, so that the ferromagnetic substance adsorbed on the permanent magnet bar is automatically separated and discharged from the iron removal port.
