Self cleaning rotary magnetic separators

Self cleaning rotary magnetic separators

The self cleaning rotary magnetic separators do not need to be manually pulled for iron unloading, but automatically remove iron on surface of magnetic bar through external control device. If you want to realize iron self cleaning or need easyclean magnetic separators, whether stop the production line will be according to site requirements. Unlike Eriez magnet and Bunting magnetics, all the magnets used in our mag filter and magnetic separator machine are from China, the biggest magnet producer in the world.

The self-cleaning magnetic rotary grate can continuously and automatically remove iron in product and keep sluggish product flowing freely. This unite is always installed where require frequent cleaning in vertical closed chutes and ducts or hard-to-reach locations. Its rotating magnetic bars are regularly pulled and drawed. Adopt specially designed scraper device to remove miscellaneous iron, or add another layer sleeve outside the rotating magnetic rods, clearing the iron by automatically separating the sleeve and magnetic rods.The magnet bars are moved in a position outside of the blanking area. Then, the ferrous iron on magnet will be scrape out or be cleared.
