kinetics of fine wet grinding in a laboratory ball mill

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

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.

fine dry grinding in ball mills. An analysis of fine dry grinding in ball mills ScienceDirect. Abstract. The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is firstorder at first, but the rates of breakage decrease as fines accumulate in the bed.
