A cement mill (or finish mill in North American usage) 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 single-chambered) allowing the use of different sizes of grinding

Variables in Ball Mill Operation 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 In ball milling

The idea of using a mixture of balls and pebbles at a mill speed suitable for ball-milling was revisited in this investigation using a normal spectrum of pebble sizes (19-75 m) Batch tests in a pilot-scale mill (0 57 m diameter) were used to compare ball-milling to various ball/pebble mixtures The mill power was measured online by monitoring lateral torque on a freely suspended motor
