Should the slurry density in a grinding mill be

2007-7-1  The slurry density or pulp percentage of solids and the size of the grinding media are often considered for ball mill optimization. Laboratory grinding tests were conducted to identify possible interactions between the two variables and the fineness of the ground product. Preliminary results show that there is no need to adjust mill slurry density when adjusting the size of the grinding media in a ball mill.

Solids Choose the Right Grinding Mill Chemical

2010-9-13  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

HIGmill high intensity grinding mill TON Outotec

The mill heights can be varied to optimize the media load and power input for specific applications. Chamber volumes range up to 50,000 liters with corresponding drives ranging up to 6,500 kW. The HIGmill is the only ultrafine grinding technology in commercial use that can use small-size high-density grinding media in mill
