The primary function of Ball, Pebble and SAG mills is to grind, crush or mix materials into a finer grade of quality as required. Often the use of mill grinding acts as the stepping stone to larger processes which heavily depend upon the refinement of materials or physics related reactions induced by grinding and crushing.

In pebble and ball mills quite often charge volumes close to 50 % are used. In a pebble mill the pebble consumption ranges from 3—15 % and the charge has to be controlled automatically to maintain uniform power consumption. The volumetric density of a rod and a ball charge is around 4.9 ton/m³ (310 lb/cu.ft) corresponding to 37 % void space. ...
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …
