The invention relates to a mineralizer for
cement production, and in particular, relates to a composite mineralizer for
barium calcium phosphoaluminate
cement. The composite mineralizer for the
barium calcium phosphoaluminate
cement comprises the main chemical components by the
mass percentage: 20-54% of Fe2O3, 13.5-33.3% of SO3, 13.5-20.8% of MgO, 5-10.4% of CaF2, and 13.5-16.5% of Na2O or K2O, wherein the mixing
mass percentage of the composite mineralizer in a
barium calcium phosphoaluminate cement
raw material is 1.25-10%. According to the composite mineralizer, SO3 comes from a variety of
industrial waste gypsums, MgO comes from high-
magnesium limestone, Fe2O3 comes from steel
slag, and Na2O or K2O comes from cement main
raw material impurities. According to the composite mineralizer for the barium calcium phosphoaluminate cement, cement clinker formation is promoted by introducing the compound mineralizer, the
calcination temperature is reduced by 150-200 DEG C, the formation of a main mineral phase barium calcium phosphoaluminate is significantly promoted, a conventional
rotary kiln production line can be applied to production of the barium calcium phosphoaluminate cement, the large-scale production is facilitated, and energy saving and consumption reduction of the production process are achieved.
