Analysis of vertical roller mill performance with changes in

The vertical roller mill (VRM), including powder separation and crushing sub-systems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller Abstract. 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 Operational parameters affecting the vertical roller mill

Cement grinding Vertical roller mills VS ball mills

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.for Loesche Vertical Mills Variable clocking • 50 / 100 ms: Signal detection • 1 second 10 minutes: Signal evaluation • Material grindability • Material temperature • Material moisture • Mixture composition • Composition of raw material • Grinding roller wear • Fineness (Blaine) or residue (VOA) • Mill motor speedPROCESS OPTIMISATION FOR LOESCHE GRINDING PLANTS
