what is ball mill critical speed

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is thespeed 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.

    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 between55% to 75% of critical speed.

    The "Critical Speed" for a grinding mill is defined as therotational speed where centrifugal forces equal gravitational forcesat the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at100% critical speed.
