2.2 Rotation Speed Calculation of Ball Mill \ Critical Speed_ and the diameter and speed of the mill can be considered appropriately. Formula (1-15) is an empirical formula for spherical diameter and feed size. the steel ball ratio in the mill can be calculated with reference to Fig. 2-1 (suitable for cement mill, other mills can refer to).

Critical speed is the speed at which the centrifugal force is equal to the gravitational force. Normal mill speed is 70 to 80% of the critical speed (Fig 1.3). For example if the critical speed is 18 rpm, mill speed will be 15 rpm. If your mill speed is more than the critical speed and the centrifugal action >

Mill speed is generally referred to as a percentage of critical, which is defined as the speed at which an infinitely small particle just follows a smooth shell lining in its motion. An increase in the mill speed will give a directly proportional increase in mill power but there seems to be a square proportional increase in the wear.

The critical speed (rpm) is given by: n C = 42.29/√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, allowing the use of different sizes of grinding media.
