The effect of slurry rheology on fine grinding in a ...
Abstract 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.
