Applying grindcurves to mill operation and optimisation
Grinding is driven by the mill load – as defined by the density, volume, and size distribution. A change in feed type changes the mill contents, which in turn changes the grinding rates, which changes the mill contents, etc. with the mill responding in a non-linear manner to the change until a new point of equilibrium is reached.
