In a wet mill, on the other hand, particles are dispersed in a liquid slurry and pumped through a grinding chamber. The particles ride along in the liquid and are crushed among the grinding media. Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size.
