Cement
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
Everything you need to know about clinker/cement Grinding
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. Hard burning may be necessary when the fuel burning is not optimal.
