speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter. The AT RITA mill speeds also decrease
