The WCG series non-magnetic roller is a non-magnetic straight parallel roller. It is made from imported non-magnetic materials and specifically processed, installed beneath the belt of a suspended magnetic separator at the bottom of a belt conveyor. The non-magnetic roller is mounted 50-150mm above the bottom flat roller of the belt conveyor. It is used in conjunction with suspended magnetic separators. When material passes over the non-magnetic roller, the material is in a scattered state, and iron impurities mixed in the middle or bottom of the material are exposed, which helps the separator effectively increase the iron removal rate.
