Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Ball milling is one of the few unit operation that improves
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
Jan 01, 1983· Afton claims that the variable mill speed has been useful for preventing liner wear while processing soft ore (Pazour, 1978). Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent.

I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed. I wanted it to turn as fast as possible to speed grinding, but not so fast that centrifugal force pins the balls to the wall of the drum preventing them from tumbling over each other.
