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 normal grinding, both dry and wet.

Kinetics of dry grinding of quartz glass (fused quartz ...

We studied the kinetics of dry grinding of quartz glass in a ball mill. We determined the dispersion of the powders at different stages of grinding and showed that it is markedly retarded with the attainment of a specific surface in the powder of about 14,000 cm 2 /g.. The dispersion and degree of polydispersion of the powder for different grinding times are characterized.
