ball mill critical speed formula . 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 although this depends upon feed input size - mills .

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
