Motion and stress intensity of grinding beads in a stirred

Experimental investigations concerning the comminution of limestone in a stirred media mill have been carried out. The results show that the circumferential velocity of the stirrer discs as well as the density and the size of the grinding beads affect the specific energy consumption necessary to achieve the required product fineness. The influence of these three operating parameters on the
