Ball Mill | PPT
The document discusses the ball mill, which is a type of grinder used to grind materials into fine powder. It works on the principle of impact and attrition, where balls drop from near the top of the shell as it rotates to grind materials placed inside. A ball mill consists of a hollow cylindrical shell that rotates about its axis, with balls ...

Ball mills produce 1 to 50 ton/h power of which about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batch-operated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.
