The formula for critical speed is CS 1/2 (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS 265.45/ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.

Critical speed | KSB

Critical speed (n k) is the rotational speed at which acting dynamic forces cause a machine component (e. g. shaft, rotor) to vibrate at its natural frequency (also referred to as intrinsic frequency, f i) and can even result in resonant vibrations throughout the entire machine and pump set.This effect has the potential to damage fast rotating machinery but can be minimised when such
