# Derivation To Calculate Critical Speed Of Ball Mill ## Ball Mill Critical Speed - Mineral Processing & Metallurgy

Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.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. N c = 42.305 /sqt(D-d) N c = critical speed of the mill.SAGMILLING.COM .:.
