The modular vertical roller mill for grinding cement raw material, cement clinker, and additives with an installed power of up to 12,000 kW was specifically designed to meet the demand for increased grinding capacities and optimized maintenance concepts. Today's cement plants can now be designed with the one-mill concept for both raw The VRM is a type of grinding mill that uses a vertically oriented, multi-level cylindrical roller to grind materials into extremely fine powders. The key components of a VRM are the grinding rollers and the grinding table. The grinding rollers are hydraulically loaded and held against the grinding table by means of hydraulic cylinders.Vertical Roller Mill in Cement Plant ballmillssupplier

For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10].The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Energy-Efficient Technologies in Cement Grinding IntechOpen
