High pressure grinding rolls (HPGR) applications in

2006-2-1  Tube mills having multichambers 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 second chamber while
