Copper ore grinding in a mobile vertical roller mill pilot plant

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 LOESCHE-MILLS. Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry.max limit of raw mill grinding roller liner wear
