This roller that also called magnetic pulley or dry agglomerate magnetic roller has two categories: full magnetic and half magnetic. It is a rotator magnetic separator, and can separate the ferromagnetic and non-ferromagnetic continuously. It achieves excellent results for operation of purification and iron recycling of grainy, powder and bulk material, also performs in a guard for crusher, presser and ball mill. It can match with the conveyor DT-75 and AD-80 to instead of driving roller. The advantages listed below: high magnetic density, large depth, maintenance free, not use electric power and good magnetic stability. This roller is widely used in mine, electric power, magnetic separation machine, metallurgy, chemical industry and building material.
