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.

Aug 01, 2009· The viscometer measures viscosity continuously as it builds over time, while rotating the spindle at a defined speed, say 100 rpm at the outset. When the torque reaches a defined maximum, say 95% for example, the spindle speed automatically drops by an order of magnitude to 10 rpm, and the measurement continues without interruption.
