The Vertical Roller Mill (VRM) is a large piece of equipment for grinding materials and is usually used in the production fields of milling slag, cement raw material, clinker, and coal. With the development of social productivity, the grinding industry is making increasing demands on the production capacity and efficiency of equipment, and the size of VRMs is also increasing.
grinding using standard bond grinding calculations based on population balance models is successfully applied [4, 38]. Various grinding laws, energy relationships, control factors and controller design for cement grinding are discussed in [37]. Figure1. Vertical roller mill for cement grinding [13]. VRM shown in Figure1 uses hydraulically hard
Several grinding methods are available in cement industry depending upon the material to be ground. In cement production process, about 26% of the total electrical power is used in grinding the raw materials. During grinding process, the energy obtained from the rotary burner is consumed. In this study, the first and second law analysis of a raw mill is performed and certain measures are ...
