 · Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material.

Depending on the form of the body, ball mills are differentiated as cylindrical, tubular, and conical. Depending on the discharging method, they are also differentiated as: • Mills with free discharge of ground product through a hollow trunnion. • Mills with discharge along …

Ball mill is a widely used and important equipment in the ore production line. In order to improve its performance, the ball mill becomes more and more complex. Such a large and complex equipment, once failed, will inevitably cause enormous economic losses, so it is very important to master some of the common fault treatment methods of ball mill.
