Cement grinding Vertical roller mills versus ball mills

adjustable dam ring (Figure 4). A higher dam ring will result in a thicker grinding bed corresponding to a longer retention time of the material on the grinding table. The material will thus receive a higher energy input before leaving the grinding table, resulting in a lower circulation factor via the separator and thus a particle size

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.
