Ball mills generally work in a "dropped" state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a "dropped" state.

The critical speed (rpm) is given by: n C = / √ d, where d is the internal diameter in metres. 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 ...

06/08/2015 · If speed of rotation is low, it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high, the balls cling to the drum walls due to centrifugal force. Therefore, intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed ...
