One contribution to minimise the increase is to use more efficient comminution equipment. Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.
