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. T

UMS mills. 1.2 Principle of Operation In ball mill, ball has to be charged around 30-32% in first and second compartments. Balls are in the range of 50-90mm in coarse and 15-50mm in fine grinding. Grinding of material takes place by means of collision or attrition or tumbling action takes place between the balls and the charge.

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
To produce powdered cement, the nodules of clinker are ground to the consistency of powder. Grinding of clinker, together with additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in combination with roller presses, roller mills.
