  • Ball Mills Or Vertical Roller Mills: Which Is Better

    Vertical roller mills Vs ball mills has long been a raging debate in the cement industry In spite of the fact that vertical roller mills have been aroundcement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materialsCement grinding Vertical roller mills versus ball millsof the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%90% Vertical mill process features: (1) The structure is simple, the vertical mill installation is adopted, the floorThe difference between vertical roller mill and ball mill

  • An energy based comparison of vertical roller mills and

    The sequence to evaluate the vertical roller mills consisted of a laboratory jaw crusher, a rod mill and two ball mill stages with differing grinding media The dimensions and settings of the laboratory mills are given in Table 1 and are illustrated in details in (Boehm and Flachberger, 2006) The jaw crusher used is a standard jaw crusherare too large to be fed into the tube (ball) mill (5) Ground materials are dried by the flue gas from the kiln Fig2 Schematic process flow of vertical roller mill for grinding of raw materials Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan Results Table Energy saving effect of the vertical roller mill Ball millVertical roller mill for raw Application p rocess materialsThe power ingesting of a grinding process is 5060% in the cement production power consumption The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills The process variables in cement grinding process using VRM are strongly nonlinear and having large timePROCESS CONTROL FOR CEMENT GRINDING IN
