Aug 15, 2012· Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches. I'm not sure how the value is derived, but it is based upon inches. Critical speed = / sqrt (jar ID media diameter) Optimal speed is 65% of the critical speed.
Note that the critical speed of the mill is calculated as follows: Critical speed (in rpm) = /sqrt(D d) with D the diameter of the mill in meters and d the diameter of the largest grinding ball you will use for experiment (also expressed in meters) Then again, a cataracting motion produces a coarser grind.
