ATTRITOR GRINDING MILLS AND NEW DEVELOPMENTS
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 (1050) 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 8001200).

A BASIC UNDERSTANDING OF THE MECHANICS OF
