How do you prevent Raymond mill'sflower rack is breaking?

Raymond mill of plum blossom once damaged, will be affect the operation of Raymond mill, but also his removal is not very convenient, Raymond mill manufacturer requirements very well about the quality of the plum flower racks, avoid Raymond mill plum flower frame deformation or fracture.
One possibility: only in the center of the Raymond mill host through gear drive shaft rotation, the central axis of the upper frame connected to one of the main parts of plum, roller shaft installed in the plum flower shelf, the plum flower frame by host gear drive and rapidly rotating, stationary rings, electromagnetic vibrating feeder send material quantitative continuously and evenly to people within the host, between grinding roller and grinding ring by grinding. Because the airflow is drawn from the lower part of the grinding ring to the tangential direction, the grinding zone between the grinding roller and the grinding ring is mixed with dust into the pneumatic classifier of the mill. There are three grinding rolls on the plum rack, not only around the center axis, but also the roller itself. Such friction and material deposition caused the plum flower frame to operate unflexibly.
Two kinds of possibility: is the most vulnerable to the possibility of that iron is contained in the material, cause the grinding roller and grinding ring face barriers in the grinding, make gear cannot turn, and the host in operation so as to break the plum blossom, Raymond mill is prohibited within the iron material entering the mill.
