Raw material fluorolimestone adding method
The invention provides a raw material fluorolimestone adding method which is characterized by comprising the following steps: (1) selecting high-phosphorus limestone which contains calcite (CaCO3) asa main mineral substance and contains a small amount of quartz (SiO2) and fluorapatite Ca(PO4)3F; (2) a raw material proportioning scheme: comprehensively considering raw material components, and controlling three rates to be as follows: KH = 0.90 +/- 0.02, SM = 2.8 +/- 0.1 and IM = 1.3 +/- 0.1; (3) carrying out a raw material burnability experiment, namely grinding the clinker by using a mortar until the clinker can completely pass through a 80 [mu]m square hole sieve, and determining the content of f-CaO in the cement clinker by using a glycerol-absolute ethyl alcohol method; and (4) testingthe strength of the cement paste. When the content of P2O5 in the clinker is 0.05%-1.50%, the mineral crystal form in the mineral phase of the clinker develops well, and the A ore is more.
本发明提供一种生料氟石灰石添加方法，其特征在于，包括：(1)选用高磷石灰石，且该高磷石灰石的主要矿物质为方解石(CaCO3)，含有少量的石英(SiO2)和氟磷灰石【Ca(PO4)3F】；(2)生料配料方案，综合考虑原材料成分，三率控制在：KH＝0.90±0.02，SM＝2.8±0.1，IM＝1.3±0.1；(3)生料易烧性实验，用研钵将熟料磨细至能够全部通过80μm的方孔筛，采用甘油—无水乙醇法测定水泥熟料中f‑CaO含量；(4)水泥浆体强度的实验。本发明熟料中P2O5含量为0.05％～1.50％时，熟料矿物相中矿物晶形发育良好，A矿较多。
