Generally there is no fixed rule; however tube mills have the ratio of 3 to 6: 1 and ball mills are of 2: 1. Residence time depends on mill size, grindability of feed and conditions of grinding. Power input >>> Fraction of mill volume occupied by the grinding charge.
It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.

Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
