    Also wet grinding can be used when the final product size is extremely fine since production of nanoparticles is possible with wet grinding. Pigments for inks and paints might be ground in the medium in which they are to be suspended. Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher.
