Experimental study on the grinding rate constant of solid ...
Jan 22, 2002· Fig. 1, Fig. 2, Fig. 3 show examples of the relationship between the mass fraction of feed size and grinding time using balls with a diameter of 20 mm and the materials of silica glass, limestone and gypsum, respectively. They exhibit almost linear relationships when plotted on semilog graph paper, and it is possible to calculate the grinding rate constant K 1 of Eq.
