Numerical Investigation of Vertical Roller Mill Operation …

When higher rolling resistance is applied due to particle shape complexity at less mill speed, more vertical force is exerted on the roller, and the roller speed is insensitive to rolling resistance. This study provides the basis for further experimental investigations on industrial-scale VRM and supports the design optimization of the VRM.
