Grindability Studies of Mineral Materials of Different Morphology
No8 Coal by flotation Ozkan et al [15] studied the kinetics of wet versus dry grinding of lignite by a porcelain mill and found that wet milling is more efficient to produce finer products Kotake et al [16] studied the effect of dry and wet grinding conditions on fineness and shape of particle size distribution of the product in a ball millDry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size In contrast, wet grinding uses a process of recirculation The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achievedWhat Are the Advantages of Wet Grinding vs Dry Grinding?
