Vertical roller mill optimisation
Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill.
