The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones.
Ball mills are normally operated at around 75 of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size – mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.

High energy ball mills have been used to prepare energetic materials including metastable alloys reactive composites and fine powders The three main mill types are shaker planetary and …
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.
High energy ball mills have been used to prepare energetic materials including metastable alloys reactive composites and fine powders The three main mill types are shaker planetary and attritor mills summarized briefly in Table 1 A common feature for all types of mills is that the energy transferred from the milling tools to the powder being milled is sufficient to cause plastic
