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 overground. This can increase preheater dust loss and

Rawmill
A raw mill is the equipment used to grind raw materials into " rawmix " during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the
