Principle of Ball Mills. The optimum rotation speed N of ball mills depends on the size of the grinding media, grinding method (dry or wet), presence of lifters, and size of the mill. In general, ball mills specifications are expressed as the ratio of the critical speed Nc to the optimum speed N (N / Nc).
