Better and cheaper cement: Optimising raw material properties

Figure 2 shows how even relatively small increases in raw mix quartz sand at one cement plant cause large reductions in 1 day mortar strengths once the sand addition rate exceeds 4%. However, grinding to a lower residue to reduce the coarse fraction is not usually a practical solution, as mill rates are reduced and the softer components are ...

Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have drying function besides grinding.
