    Feb 01 2011 · 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
