Apr 19, 2021 The resistance to grinding was expressed as a constant parameter K R in the model proposed by Rittinger for grinding fine particles and was found to be 56, 40 and 14 J mmcm 3 for clinker, gypsum and limestone, respectively. Additions of limestone, gypsum or both materials to clinker had a lowering effect on K R. The interaction between each component composition and blends grindability has a linear behaviour in terms of volume fractions and the individual resistances to grinding.
