Among the challenges mill optimisation tries to address is too little material in the mill, or too much. Too little leads to critical impacts between the grinding media and the mill liners, damaging both elements without producing value. If the mill is overfilled with mined material, on the other hand, this results in grinding inefficiencies.

How Ball Mills Lifter Bar Affects Charge Motion

Aug 08, 2018 The performance of a ball mill is known to be affected by the design of the liners. A proper liner must key the ball charge to the mill shell in order to maximize the tumbling action with a minimum of slippage, and at the same time it must protect the mill shell from damage. There are two important features that are common to all three figures.
