Ball Milling Ball Speed

How can I determine the best RPM for Dry Ball Milling


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)

Ball Mill an overview | ScienceDirect Topics


For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy.

Ball mill Wikipedia

Ball Milling Ball Speed 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.
