• #### Ball Mill Critical Speed Mineral Processing & Metallurgy

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

• #### what is the critical speed of ball mill

The critical speed can also be derived by 42.3/D0.5 where D is the diameter in METRES. For instance, a 90cm diameter ball mill has a critical speed of 44 rpm. For efficient milling, the critical speed is too high you need now to determine the optimal speed which is about 70-75% of the critical speed. For instance a 90cm diameter ball mill

• #### Mill Speed Critical Speed Paul O. Abbe

In most cases, the ideal mill speed will have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way. The ideal mill speed is usually somewhere between 55% to 75% of critical speed.
