ball mill working principle | Henan Deya Machinery Co., Ltd.

Ball Mill Working Principle. Grinding is usually performed wet, although in certain applications dry grinding is used. When the mill is rotated, the mixture of medium, ore, and water, known as the mill charge, is intimately mixed; the medium comminuting the particles depends on the speed of rotation of the mill and the shell liner structure.
