Ball mill internals can play a key role in a preventative maintenance programme. Crucially, mill internals protect the mill shell. Furthermore, mill lining plates are subject to wear which in turn can lead to adverse operating conditions. For example, one of the most abrasive processes that the mill has to endure is the processing of fresh feed. If the mill is filled with too low a ball charge

The ball mill is used for the grinding of a wide range of materials, including coal, pigments, and felspar for pottery, and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the hold-up in the mill, until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.
