During clinker grinding, gypsum is easy to grind, hence it increases the concentration of finer particles. Likewise, the fly ash does the same. But the blast furnace slag adds to the concentration of coarse fractions. Gypsum at clinker grinding controls the setting time of cement. Addition of gypsum retards the setting process.

In Figure 1a, both PSD graphs show the typical 'shoulder' (range 1-10μm) coming from the limestone. The clinker in the ball mill is clearly less ground than in the VRM, which will result in lower mechanical strength. Although the VRM grinds the clinker to a higher degree, the fineness of the limestone is not increased proportionally.
