Media Milling, Dry and Wet. Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high- or low-energy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.

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 [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.
