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. Usually, some form of separation follows size reduction. The most common is simple screening, in which the screen openings are selected to pass the desired size range and retain material that is too large.
