How can I determine the best RPM for Dry Ball Milling ...
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.
