The working principle of ball mill - Meetyou Carbide

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

Automation and Control in Cement Industries

grinding can ensure that the overall control aim is reached, and that the other controls are auxiliary ones. Therefore, these three areas are investigated next. The above operations-triplet can theoretically be controlled together, however, this seems to be, in practice, a large-scale system, therefore a reasonable decomposition is necessary.
