The vertical coal mill consists of many parts, among which the vertical mill grinding table and the grinding roller play a crucial role in the material grinding. The primary function of the table is to support the material bed and transfer the force generated by the roller to the lower speed reducer, and also transmits the torque of the speed.
Each grinding roller is supported separately, and the overhaul door on the middle housing can be opened during examine and repair. The grinding roller can be easily turned out of the coal mill by the hydraulic cylinder, and the roller sleeve can be easily disassembled and removed for convenient overhaul and maintenance. 12.
