The deviations of the ratio of liberation between the test points in the same particle size range are small, although the mill settings are quite different. This confirms the minor effect of the varied mill parameters, like dam ring height and grinding pressure, which are not effecting the fineness in the first place. It is concluded that liberation cannot be …

Similarly ball size influences a grinding mill performance but the effect of this variable is independent of the slurry density. Therefore once an optimum slurry density has been identified for a given grinding mill, ore and ball charge, other ball sizes tested in that mill should yield close to optimum performances at the operating density.
