Power predictions for a pilot scale stirred ball mill
1996年3月1日 The slurry density also had a strong influence on the power draft. Thus changing the slurry density by only 10% from 65% to 75% caused the mill power draft to increase from 4 kW to 6 kW. From the correlation alone, the slurry density had a stronger effect than the mill speed. It had a power of 2.95 as is seen in Fig. lb.
