an analysis of fine dry grinding in ball mills

Jan 01 1981 · 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 It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill indicating that the cushioning action of fines affects the whole breakage process
