Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...

To increase the efficiencies of crushing and grinding, new crushers and mills should be developed. In this direction, highpressure grinding roller (HPGR) mills, developed in the 1980s (, Schönert 1979, 1988), represent a relatively new technique in mineral processing. The HPGR mills yield higher energy efficiency than ball mills, probably ...
