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 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.Cement grinding Vertical roller mills VS ball mills

Copper ore grinding in a mobile vertical roller mill pilot plant
A study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits. Wear rate is another criterion that is needed to be considered. In this context, Erkan et al.
