Fig. 2 depicts the cumulative particle size curves for the wet and dry grinding under different grinding times. As the grinding time increased from 1 min to 10 min, the dry grinding indicated a faster reduction of the average particle size (d 50) compared to the wet grinding. This is caused by the difference in breakage energy and mill ...
