The kinetics of slowing down of breakage rates for fine wet grinding of 20×30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowing-down effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions.

2017-8-21  Keywords: fine wet grinding; ball mill; slurry rheology; breakage rates 1. Introduction It is generally observed that dry and wet grinding of materials in tumbling ball mills to very fine sizes can lead to the slowing down of the overall grinding process (Austin et al., 1984; Frances and Laguerie, 1998; Yekeler et al., 2001). This effect ...
