Study on Particle Characteristics of Cement by Vertical Roller Mill :
Abstract:The particle characters and their physical properties of vertical roller mill finish grinding cements were studied in this paper. The difference with roller press-ball mill combined grinding products was also analysis. The results were shown that the particle size of the vertical roller mill finish grinding cements was more evenly distributed at the comparative average size. The proportion of the particles under the 3um and on 60um has fallen off a little; the average circularity and slenderness ratio were nearly same with combined grinding process, but the proportion of high circularity particle is lesser, and the particle shape were slightly inferior with the cement produced by combined grinding process; the physical properties were nearly same with the combined grinding cement except the longer setting time. So the cement produced by vertical roller mill finish grinding process is satisfied for the usability requirements
