ball mill rates for quartz grinding

The effect of ball and mill diameters on grinding rate

May 01, 1985· For dry ball mill grinding operation, the effect of ball and mill diameters on grinding rate parameters of the size-discretized population balance model has been investigated for quartz, limestone, a soft cement clinker and a hard cement clinker. Experiments were performed in three mills of 29.2, 40.6 and 61.0 cm diameter.

Kinetics of fine wet grinding in a laboratory ball mill

Jan 15, 2001· Grinding was carried out in the laboratory ball mill described in Table 1, at a low ball load of 20% of the mill volume filled with the ball bed and a low powder load corresponding to a formal interstitial filling of void spaces of the ball bed of U=0.5. These conditions were chosen since it is known that they give first order grinding kinetics for normal grinding, both dry and wet.
