Abstract (en)
[origin: CA2701139A1] The invention relates to a method for producing Portland slag cement and blast furnace cement by means of a two-stage grinding process comprising the following steps: a) Portland cement klinker is introduced into a first mill, the cement mill (24) for pre-grinding; b) the product discharged from the cement mill is fed directly and/or via an intermediate reservoir to the feedstock of a dynamic sifter; c) slag sand powder or slag sand grit is also introduced into the feedstock of the dynamic sifter; d) coarse product that is discharged from the dynamic sifter is fed to the feedstock of a second mill for fine grinding; e) the product discharged from the second mill is fed to the feedstock of the dynamic sifter; f) a sulfate carrier is supplied to the first mill, or to the feedstock of the dynamic sifter or to the feedstock of the second mill; and g) the finely ground product from the dynamic sifter is supplied to a reservoir.
