### ATTRITOR GRINDING MILLS AND NEW DEVELOPMENTS

Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), 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.
