Even if some of them have crystallized, they are ...
1) alite size, as before. 2) C2S content, as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.
The clinker SO3 content has been recognized as having an impact on grindability. Higher SO3 in clinker results in a reduction in grindability and increases specific power consumption per ton. Also, increasing SO3 …
