Review on vertical roller mill in cement industry & its
Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 45–70% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.A study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits. Wear rate is another criterion that is needed to be considered. In this context, Erkan et al. (2012) in their study compared the wear rates of rod-ballCopper ore grinding in a mobile vertical roller mill pilot plant

Industrial application of system integration updated technology
Secondly, concerning the technology updated project of the TRM53.4 raw material vertical roller mill owned by YongDeng Qilianshan Cement Ltd. Co., the industry application scheme adopted in this project is presented, and the practical application effects are studied in detail, which show that this technology can increase the production of the raw material Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAG-ball mill circuit, which was 20.11 kWh/t, was reduced to 11.40 kWh/t by using Copper ore grinding in a mobile vertical roller mill pilot plant
