The common maintenance practice for worn VRM roller and table wear liners is to reweld or hard face the worn surface. This means regular stops to mill operation. But because the wear rate in a VRM varies, depending on feed materials and product fineness, the number of times maintenance is required over a given time period is variable.

This study investigated the effect of table speed (mill speed), roller and table gap, dam ring height, and rolling resistance of material using the discrete element method in an industrial-scale VRM. Simulation results showed that the rolling point is moved near the outer diameter of the grinding table as the mill speed increased.

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 and particles.
