ball mill speed calculation formula for wet grinding

SAGMILLING.COM .:. Mill Critical Speed Determination

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 shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Enter the mill diameter inside the shell (excluding liners).
