small grinding media perform in industrial grinding mills? The use of small grinding media in regrind mills proved that finer grinding can be achieved at lower energy consumption In ball mills smaller grinding media versus 25 mm media generate a power saving from 10% to 44% In vertical stirred mills the power saving increases from 20% to 60%

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

If media does happen to collide the chances are against the media colliding with a pigment particle between them Of course the probability increases as the solids level approaches 100 percentbut even then this happens in the low energy are of the mill so the energy levels are not significant Media Selection
