  • Grinding process and particle grading and water demand

    The process technology of this cement grinding is still limited in China. In fact, the cement vertical grinding final grinding products can be compared with the ball mill, which can meet various engineering needs. The selection rate of the cement vertical grinding final grinding process has shown an increasing trend year by year.Modern Processing Techniques to minimize cost in Cement,The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 15 kWh/ ton of raw mix whereas the VRM motor uses 7 8 kWh/ ton.
