An analysis of fine dry grinding in ball mills - ScienceDirect
1981-1-1 · The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed. It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill, indicating that ...

Reagglomeration phenomena in fine dry grinding of coal ...
1997-5-1 · Investigations were performed on fine grinding of bituminous coal in a laboratory-scale pulverizer. The results indicated that the breakage behavior at relatively coarse sizes (i.e., greater than about 20 µm) is essentially “normal.” However, at fine sizes (i.e., less than about 10 µm), there is clear evidence of reagglomeration. A simplified population-balance model for
