Ball mill - Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axi

Difference Between Cement Vertical Mill and Ball Mill
Compared with the ball mill, the vertical mill can save 30% -40% of energy consumption, and has low vibration, which is a low energy consumption. Energy Saving and Noise Reduction When the vertical mill is in operation, the grinding roller does not directly contact the grinding disc, and the vibration is small, the noise is low, and the sound is soft.

Clinkers are ground in ball mills and tube mills after controlled cooling. The cooling rate of clinkers affects the strength-gaining properties of cement. About 3-5 % gypsum is added during grinding to the cooled clinkers to prevent flash set. Closed-circuit grinding is done in tube mills. A cyclonic separator ensures proper particle size ...
