What's raymond mill plum frame function and deform reason?

Plum frame is raymond mill main spare parts, plum frame generally adopt high hardness, good wear resistance material made, such as hard nickel-iron, high chromium cast iron, high manganese steel, etc. In addition to plum frame raw materi, manufacturer and process method are also important, for example, hard nickel-iron rollet sleeve using metal mold or centrifugal casted, hardness is 700HB, using sand mold casted hardness is 500HB. Plum frame position: grinding roller connect plum frame. Plum frame bottom is blade barrel, blade barrel fixed on plum frame, raymond grinding mill main host bottom have a big recoil bearing, so, raymond mill main shaft won't fall off, plum frame at main shaft top and be fixed.

Generally condition, as long as raymond mill normal working, there is no hard material fall into the grinding area and stumble main shaft, plum frame won't be deform. Raymond mill main host through transmission device drive center shaft rotation, center shaft top connect plum frame, roller shaft installed on the plum frame, plum frame drive by main host transmission device and fast rotation, grinding ring fixed, electric vibrating feeder make raw material fixed quantity, uniform and continous feeding to grinding chamber, grinded by grinding roller and grinding ring force. As airflow from grinding ring bottom tangentially inhalation, through grinding roller and grinding ring grinding area, inclusion powder dust feeding raymond mill top wind classifier. Plum frame top installed three grinding roller, not only revolving around the central axis, but also grinding roller itself due to friction rotation. Thus, through friction and raw mateiral sedimentary lead to plum frame unstable working.
