Process for producing clinker by using yellow phosphorus slag as mineralizer
The invention discloses a process for producing clinker by using yellow phosphorus slag as a mineralizer. The process comprises the following steps: step 1, selecting raw materials: selecting the yellow phosphorus slag with proper components, the F (fluoride) content of the yellow phosphorus slag being 2.0-4.0% and the P2O5 content of the yellow phosphorus slag being 2.0-5.0%; step 2, mixing ingredients: mixing limestone, sandstone, clay, iron tailings, yellow phosphorus slag and the like. The preparation method comprises the technological processes of raw material selection, ingredient mixing, raw material drying and grinding, decomposition and calcination and rapid cooling, promotes carbonate decomposition, improves clinker burnability, solves the problems of low clinker strength, high cement standard consistency water consumption, unstable adaptability to additives and poor workability of the existing Portland cement clinker due to high alkali content, and has the advantages of enhancing the clinker strength, lowering the cement standard consistency water consumption, enhancing the workability of the cement product and lowering the clinker calcination energy consumption.
本发明公开了一种利用黄磷渣作为矿化剂生产熟料的工艺，包括以下步骤：步骤1：原料选择：选取成分适宜的黄磷渣，黄磷渣F(氟化物)含量在2.0％～4.0％，PO含量在2.0％～5.0％；步骤2：配料混合：将石灰石、砂岩、粘土、铁尾矿、黄磷渣等；本发明通过原料选择、配料混合、原料烘干磨粉、分解煅烧和快速冷却的工艺流程，促进碳酸盐分解，改善熟料易烧性，解决了目前的硅酸盐水泥熟料因碱含量高导致熟料强度低，水泥标准稠度耗水量大，与添加剂适应性不稳定和易性不好的问题，具备既能提高熟料强度，又能降低水泥标准稠度耗水量，提高水泥产品和易性能，又能降低熟料煅烧能耗的优点。
