4.2x14.5 Ball Mill for cement 

Our tube grinding mill is typically designed for grinding different kinds of ores and many other grindable materials, and it can be widely used in building materials, metallurgy, chemical industry, electricity industry, and many other industrial or mining fields. 

this cement ball mill can be used for open circuit grinding, and when used in conjunction with powder classifier, it can also be used in circulatory closed-circuit grinding. 

Our tube grinding mill can be used in dry production line as well as wet production line, and the grinding process can be accompanied by dry process. this cement ball mill has advantages of strong material adaptability, strong continuous production capacity, big crushing rate, and it is easy to adjust the grinding fineness. 

Component

Shell 
this cement ball mill is horizontal shell rotating device, mainly consists of shell, mill door and liner bolts. so we require to check the mill when shut down, especially to check the liners on shell and mill door. 

Liner 
the liners of the tube grinding mill are used for protect shell in order to avoid damage to shell, please check liners regularly to avoid any loose because of bolts etc. 

Diaphragm 
Diaphragm is used to separate grinding media to avoid axial movement of media and large-size materials move to next chamber. It can control material flow and grinding speed inside the mill. 

Diaphragm plate consists of central circle, feed cone, grate plate, lifting plate, liner, diaphragm support and blind plate. Please check if there is any loose, miss of bolts, and check the condition of grate plate and blind plate. 

Main bearing 
Bearing is used to bear the weight of rotated part also impact of grinding media. the mill is supported on main bearing by hollow shaft. There is bearing cover, manhole and temperature gauge on bearing housing. 

Feeding and discharging device 
Feeding device of this cement ball mill is used to feed materials into mill. There is chute feeding device, screw feeding device and ladle feeding device. The discharging device consists of discharging grate plate, guide cone, lifting plate, discharging cylinder, drive connecting tube, drum screen, discharging cover, coarse tube etc. 
Drive device 
Drive device consists of speed motor, slow drive motor, slow reducer and speed reducer. Please check: if there is any overheat and noise of reducer oil pump. and check working condition of each element such as pressure gauge, temperature gauge, and if there is any oil leakage, etc. Please adjust oil flow as per weather condition; check if there is any noise of main oil pump, etc.
