general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.
To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of low-grade deposits become necessary. More powerful and larger mills, higher ball charges and demanding ambient conditions call for a strong partner for grinding solutions.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
