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 rod-ball ...Web
