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 lowenergy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.
