How To Derive Ball Mill critical Speed Equation

Mill Critical Speed Formula Derivation Grinding. When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell. The formula to calculate critical speed is given below.

TECHNICAL NOTES 8 GRINDING R. P. King

Since critical speed is larger at smaller radii the centrifuging layer gets thicker and thicker as the speed increases until the entire charge is centrifuging and the net power draw is zero. The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge.
