  • Operational parameters affecting the vertical roller mill

    Grinding test results for zinc ore showed that it is possible to decrease the total grinding energy consumption from 20.11 to 11.40 kW h/t by using vertical roller mill instead of AG/SAG-ball mill circuit (van Drunick et al. 2010). Vertical roller mill (VRM) technology was developed based on that and attracted interests of both manufacturers and researchers. It has been used mainly for cement raw meal grinding applications where crushing grinding classifying and drying operations were combined in a single unit.

    savings compared to conventional ball milling. The HPGR and air classification circuit used 2030 less energy than the HGPR screen ball mill circuit. While VRM was estimated to use 1030 less energy (depending on the type of VRM) than a ball mill circuit for a similar degree of comminution. A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs
