3A: Ball Mill Fundamentals. Ball Mill Dynamics The basic objectives of ball milling is the size reduction of materials, called comminution. Size reduction in a ball mill is achieved primarily by the motion of the balls in the mill. By rotation, the mill elevates the ball charge and material and drops the load upon itself.. Comminution Mechanisms

With more than 7,100 tube mills equipped all over the world, you will benefit from the best experience in the cement industry. Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge.
Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

Grinding Ball Charge in Mills: According to Levenson, the optimum grinding ball charge should be r The degree of ball charge varies with in the limit of 25 and 45%. A ball charge below 25% causes sliding of the balls. On the mill lining; a ball charge above 45% causes disturbances along the trajectories of the grinding media.
The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple.
