Preparation method of superfine slag powder
The invention discloses a preparation method of superfine slag powder. The preparation method comprises the following steps: (1) respectively drying water granulated slag, slurry slag of a foundry and barren rock; (2) respectively pre-grinding the dried water granulated slag, the slurry slag of the foundry and the barren rock, scattering, separating, homogenizing and storing; (3) feeding the grain slag fine powder, the foundry slurry slag fine powder and the barren rock fine powder into a grinding machine for grinding to obtain grain slag fine powder, foundry slurry slag fine powder and barren rock fine powder of which the specific surfaces are 400-550 square meters/KG; and (4) sequentially and uniformly mixing 75-90% of the water granulated slag, 3-20% of the slurry slag of the foundry and 3-10% of the waste rock to obtain the superfine slag powder. According to the invention, the water granulated slag, the slurry slag and the waste rock are ground into the slag micro-powder, so that waste utilization is realized, the environment is protected, the high-activity slag micro-powder can be prepared, and the production cost is reduced.
本发明公开的一种矿渣微粉的制备方法，包括以下步骤：(1)将水渣、铸造厂浆渣、废石分别进行烘干处理；(2)将烘干处理后的水渣、铸造厂浆渣、废石分别进行预粉磨后打散分离并进行均化和储备；(3)将水渣细粉末、铸造厂浆渣细粉末、废石细粉末送入磨机中进行粉磨得到比表面为400‑550平方米/KG水渣细粉末、铸造厂浆渣细粉末、废石细粉末；(4)将制备好的物料按照水渣75％‑90％、铸造厂浆渣3％‑20％、废石3％‑10％依次混合，混合均匀后即得矿渣微粉。本发明使用了水渣、浆渣和废石研磨成矿渣微粉，既实现了废物利用，保护了环境，也能制成高活性的矿渣微粉，降低了生产成本。
