Vertical Roller Mill (VRM), a cutting edge technology, can be installed to grind the hard, nodular clinker from the cement kiln instead of inefficient ball mills that can save up to 15% energy [63]. Inclusion of flexible speed drive used for cooling purpose can further reduce electricity consumption.

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/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.
