ATTRITORS AND BALL MILLS HOW THEY WORK Robert E. Schilling

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). High speed dispersers with no media run even faster rpm (1200-1800).
