Data from ball mills of a wide range of sizes are analysed using detailed mathematical models and non-linear least squares fitting techniques. This analysis reveals that the relative power inefficiency of large ball mills is due to inefficient grinding of coarse (plus 4 mm) particles in these mills. A qualitative physical hypothesis is proposed to explain this …
