Copper ore grinding in a mobile vertical roller mill pilot plant
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 The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of over-grinding and improve the grinding efficiency.

C. Obry. Karl-Heinrich Zysk. Vertical roller mills are the mills traditionally used for processing granulated blastfurnace slag and for grinding composite cements. From the energy aspect they areThis work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on Analysis and Optimization of Grinding Performance of Vertical Roller
