the rotating charge inside most industrial ball mills. Most industrial ball mills have lifters. Data from 40 ball mills show that the average critical speed is 0.73 (Morrell, 1996). Research in mill charge motion (eg. Mishra and Rajamani, 1992; Inoue and Okaya, 1994) reveals how the charge motion vary with mill speed and liner/lifter profile.
