Ball Mills  an overview  ScienceDirect Topics
The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled.

PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL
The mill is designed to handle a total ball charge of 324.5 t at loading with a percentage filling of 29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.

Cement mill  Wikipedia
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size  mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25
