IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
