Grinding Media Charge Motion inside Mill
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.
