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

Critical speed (in rpm) = 42.3/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. If you want your grind to be finer, it is the cascading motion that is your best choice...

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow...
