Everything you need to know about clinker/cement Grinding

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.

2 Major Roles of Limestone in Cement Manufacturing

The result is called clinker, which are rounded nodules between 1mm and 25mm across.
