A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 cylindrical shell rotati
The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners.
Because you want the grinding balls to experience a free-fall motion, i.e. cataracting motion, I would recommend you consider a rotational speed between 65 and 85 % of the critical speed of the mill.
This is one of the reasons why we cannot only move at high speed with the High-Z milling machine but can also powerfully mill steel. Real high speed with up to 34 meters per minute driving speed! The CNC milling machine was developed especially for even better accuracy (repeatability is about 0.01 mm) and higher driving speed.

Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary
