Rotary magnetic separators

Rotary magnetic separators

Rotary magnetic separators, also called rotary grate magnet or inline rotary magnet, is one kind of physical magnetic separators. is designed for sluggish materials that tend to plug up stationary magnetic drawer. It is mainly used to remove miscellaneous iron from materials such as easily bonding or bridging materials, and prevent material from packing and plugging up the processing line. We can design various rotary magnetic separators including easy clean structures. 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.

Rotary grate magnetic separator, also called rota grate magnet, is mainly constitutive of magnetic element, housing and gear-motor. It is often installed at the discharge of opening chute or duct system where has a lot iron impurity. This unit can be applied to rigorous environment. Its special magnetic circuit design can ensure good iron removal effect and protect downstream equipment. The easy-to-clean rota-grate magnet separator make the iron cleaning more easily by adding double-layer stainless steel sleeve on magnetic bar surface. When cleaning, manually separate the non-magnetic sleeve and magnetic element can achieve quickly iron unloading.

Characteristics and advantages
