Method for producing cement clinker by utilizing limestone waste ore and preparation method of cement clinker
The invention relates to the technical field of cement production, in particular to a method for producing cement clinker by utilizing limestone waste ore, and the cement clinker is prepared from the following components in parts by mass: 65.5-70 parts of cement clinker, 3-4 parts of desulfurized gypsum, 1.5-2 parts of phosphogypsum, 5-7 parts of fly ash and 12-18 parts of mining waste rock. The cement has the beneficial effects that the cement has the characteristics of good workability and strong admixture adaptability; the ardealite, the desulfurized gypsum, the mining waste rock and the cement clinker are reasonably proportioned and adjusted, so that a large amount of ardealite and the mining waste rock are consumed while the self-leveling cement is produced, and the comprehensive utilization of waste residues is realized.
本发明涉及水泥生产技术领域，特别是一种利用石灰岩废矿生产水泥熟料的方法，以质量分数计，包括水泥熟料65.5～70份、脱硫石膏3～4份、磷石膏1.5～2份、粉煤灰5～7份、采矿废石12～18份。其有益效果在于，水泥具有和易性好、外加剂适应性强特点；通过磷石膏脱硫石膏、采矿废石、水泥熟料进行合理配料调整，生产自流平水泥的同时，消耗大量的磷石膏、采矿废石，实现废渣的综合利用。
