Comparison of the overall circuit performance in the cement

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 India is the world's second largest producer of cement and produces more than 8 per cent of global capacity. Due to the rapidly growing demand in various sectors such as defense, housing, commercial and industrial construction, government initiative such as smart cities & PMAY, cement production in India is expected to touch 550–600 million Review on vertical roller mill in cement industry & its
