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.

Optimization Of Vertical Roller Mill

Optimization Of Vertical Roller Mill. The mills are large consumers of power as well. in the case of ball mills, optimization of the mill charge helps to minimize the power consumption of the mills. in the case of vertical roller mills, inspection of the mill internals and adjustments in the operation will bring about an improvement in the energy consumption and for production

Cement grinding Vertical roller mills versus ball mills

vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the vertical roller mill
