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
