Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
Aug 02, 2013 In Grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW Toromocho, private communications.
The formula for critical speed is CS 12 g R-r where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS 265.45 R-r. Dry mills typically operate in the range of 50-70 of CS and most often between 60-65 of CS.
