The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition

where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained Δ is a constant, which relates to wear laws For each ball size class, S i,k values are calculated using Eq

essential to efficiently grind fine particles Figure 1 shows the grinding power required to grind a sample of KCGM pyrite concentrate to different target P80 grind sizes, using a ball mill (with 9mm steel media) or an IsaMill with sand media There is little difference at coarser sizes, but below 30 microns the advantage of stirred milling becomes dramatic Ball milling simply cannot produce
