Raw material composition for cement clinker and preparation method of cement clinker
The invention discloses a raw material composition for cement clinker and a preparation method of the cement clinker. The raw material composition comprises the following components in percentage by mass: 88-95% of limestone, 1-4% of sandstone, 1-5% of iron ore and 1-4% of fluorite mineral powder. The fluorite mineral powder is added into a silicate system, and the fluorite mineral powder is used as a mineralizer, so that the clinker strength is greatly improved, and clinker granulation is reduced; and by adding the mineralizer, the thermal decomposition temperature is greatly reduced, and the comprehensive cost of the cement is reduced by about 2 yuan/ton.
本发明公开了一种水泥熟料用的原料组合物及水泥熟料的制备方法,按质量百分数组份包括:按质量百分数组份包括:石灰石88‑95%,砂岩1‑4%,铁矿石1‑5%,萤石矿粉1‑4%。通过在硅酸盐体系中通过加入萤石矿粉,萤石矿粉作为矿化剂,使得熟料强度大大提升,减少了熟料结粒;且通过加入矿化剂,使得热分解温度大大降低,水泥综合成本下降约2元/吨。
