The application of verticalrollermills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.

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.
