Studies on Scale-Up of Ball Mills
Copyright policy )Studies on Scale-Up of Ball Mills
The impetus for the work described in this paper was provided by difficulties being reported by some operators in obtaining design throughputs in large diameter ball mills. In some cases, it seems that the usual methods of ball mill scale-up based on the Bond work index seriously overestimate the throughput of large diameter ball mills; in other cases, these methods seem to have been used successfully in the design of grinding circuits containing such mills. Data from ball mills with a wide range of diameters are analyzed using detailed mathematical/numerical models. Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale-up mill behavior.
