This paper describes basic characteristics of CRIMM roll-type high intensity permanent magnetic separators, and their applications in separation of weakly magnetic limonite. The authors discuss their magnetic field's characteristics and explain their separating structure's effectiveness and rationality in separation of coarse weakly magnetic ore.

Commonly used equipment is high gradient strong magnetic separator. The method uses a magnet to separate magnetic and non-magnetic particles, isolating pure …
view more5 · High-intensity magnetic separators, or multi-roller magnetic separators, are iron removal/magnetic separation equipment for sorting weak magnetic minerals. It is widely used in limonite, manganese ore, and beach sand mineral processing. This magnetic separator uses a strong magnetic field to effectively dry separate ferromagnetic materials …
