Kinetics of fine wet grinding in a laboratory ball mill
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 Contact Us.
