    Mar 20, 2017 MATHEMATICS OF GRINDING Critical Speed:-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. Mills are driven, in practice, at speeds of 50-90% of critical speed, the choice
