Mill Critical Speed Determination. The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shells inside surface. This is the rotational speed where balls will not fall away from the mills shell. Enter the mill diameter inside the shell excluding liners.
