For example ball mills use large media normally 12 or larger and run at a low 1050 rpm the other mills such as sand bead and horizontal use smaller media from 03mm to 2mm but run at a very high rpm roughly 8001200 high speed dispersers with no media run even faster rpm 12001800

The motion of the charge that is the grinding media and the material undergoing grinding within a mill is of considerable theoretical interest and practical importance and for these reasons has been the subject of considerable study by a number of workers but even so no rigid and complete theory covering all the aspects of the dynamics of the mill charge has yet been produced
