Research of iron ore grinding in a vertical-roller-mill

2015-3-15  Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

Influence of quartz particles on wear in vertical roller

2010-4-1  The VRM has a few drawbacks: In a closed circuit VRM process, the abrasive minerals from the feed will up-concentrate on the grinding table resulting in increased wear rates. The optimal VRM production is based on fixed geometrical wear part surfaces and if these are altered due to abrasive wear, the VRM will perform unsatisfying.

Operational parameters affecting the vertical roller

2017-4-1  Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grinding circuits.
