Case 1 – secondary and regrind ball mills in copper-zinc-lead mine The choice of grinding media size to achieve ﬁ ne grinding efﬁ ciently in the range of 15 to 25 μm has always been a concern at Brunswick Mine (Staples et al, 1997). Because the recommended Bond
• characteristics of the grinding media (mass, density, ball size distribution); • speed of rotation of the mill; • slurry density in case of wet grinding operation. Quantitative estimations of these parameters can be found in [4, 5, 23]. An important characteristic of an industrial ball mill is its production capacity
