grinding should be performed where possible in open-circuit rod mills, but if fine grinding is required, closed-circuit ball milling should be used, preferably with screens closing the circuits rather than hydrocyclones in order to reduce selective overgrinding of heavy friable valuable minerals.

1. Introduction. Tube mills having multi-chambers are traditionally used for cement grinding either in open or closed circuit operations. In the first chamber, larger balls (100–60 mm) are used for coarse grinding while the smaller balls (40–15 mm) are used for fine grinding.The chambers are separated by an intermediate diaphragm which allows the passage of the fine particles to the …
