Investigating multicomponent breakage in cement grinding
During the blended cement production the components are ground within the same mill and as a result of different grindabilities, relatively harder components accumulate in coarser fractions while the softer ones accumulate in finer fractions (Schiller, 1992, Tsivilis et al., 1999).
