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 "functional performance equation for ball milling" was first presented in 1988. It has now been used successfully in a substantial number of mineralprocessing plants. This powerful, yet simple, tool provides a new level of understanding of closed circuit grinding. It shows how grinding circuit efficiency is really comprised of two distinct efficiencies. It demonstrates how circuit ...
