Dec 11, 2018· in the later cement grinding Is it possible that a high SM (around 3) increases the clinker hardness by adding silica to the clinker composition? Does a low A/F ratio (around 0,7) contributes to form dusty clinker due to the lack of cohesion/low melt viscosity, thus being unable to form big particles? Thanks in advance A:
