However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally. In internal recycling, the coarse material is conveyed by a reverse spiral or water jet back down the center of the trommel into the mill. External recycling can be continuous, achieved by conveyor belt ...

There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series.

01.01.2016· If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill efficiency factor. Other correction factors such as mill diameter and reduction ratio however do apply. The uncertainty in this correction factor means that it has little value ...
