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.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 media.

Axial transport in dry ball mills - ScienceDirect . Ball mills are used for grinding of rocks, cement clinker and lizenithne from 10 to one-dimensional diffusion equation with the diffusion coefficient decreasing with the mill speed was 75 of the critical speed required to centrifuge particles.However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed At position A, the media is held to the wall due to the following force balance Mg cos = M †‘2 (R – r)g.2012-11-26The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed the greater the wear on the rods and liners. Trade Assurance.
