Mill type overview three types of mill design are common the overflow discharge mill is best suited for fine grinding to 75 106 microns; the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns; the center-periphery discharge mill has feed reporting from both ends and the product discharges .
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 12 or larger and run at a low (10-50) rpm.
