Population Balance Model Predictions of the Performance of

1985/05/01In spite of potential theoretical and economic advantages of large-diameter ball mills, many manufacturers elect not to build them owing to what is perceived as an excessively large design risk. This is because traditional predictions for mill scale-up to large diameters are not always accurate. Alternative methods of analysis and scale-up are required.Recent studies have shown that detailed

2010/09/13Choose the Right Grinding Mill -- Consider the feed material's nature and the milling's objective. 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
