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.

By contrast, attrition milling relies on a horizontal rotating vessel filled with a size-reduction solution. Treated to grinding media, the materials tend to be turned into free-flowing, spherical particles. This method, which includes the ball mill, can reduce 1,000 micron (20-mesh) particles of friable materials down to less than 1 micron.
