Cement with iron powder sludge replacing iron raw material and preparation method thereof
The invention discloses cement with iron powder sludge replacing an iron raw material. The cement is prepared from, by weight, 60-68 parts of limestone, 6-10 parts of sandstone, 6-8 parts of carbide slag, 2-3 parts of the iron raw material, 6-12 parts of iron ore sludge, 2-3 parts of filter residues and 2-3 parts of shale. The invention further provides a preparation method of the cement with the iron powder sludge replacing the iron raw material, and the preparation method comprises the following steps: S1, adding the limestone, the sandstone, the carbide slag, the iron raw material, the iron ore sludge, the filter residues and the shale into mixing equipment in proportion, and uniformly mixing through the mixing equipment to obtain a mixed material. According to the invention, the iron ore sludge is reasonably matched and used, so that the production cost is reduced, considerable economic benefits are created, extra revenue is created for the country, waste utilization is realized, the environment is protected, the social response is good, the win-win situation of economic development and environmental protection is realized, and a good situation of collaborative development of local and enterprises is formed.
本发明公开了一种铁粉污泥替代铁质原料水泥，包括以下重量份配比的：石灰石60‑68份、砂岩6‑10份、电石渣6‑8份、铁质原料2‑3份、铁矿污泥6‑12份、滤渣2‑3份、页岩2‑3份；本发明还提出一种铁粉污泥替代铁质原料水泥的制备方法，包括以下步骤：S1，将石灰石、砂岩、电石渣、铁质原料、铁矿污泥、滤渣、页岩按比例加入到混合设备中，通过混合设备进行混合均匀，得到混合物料。本发明通过对铁矿污泥的合理搭配使用，降低了生产成本，创造了可观的经济效益，为国家创造了额外的税收，还实现了废物利用，保护了环境，社会反响良好，实现了经济发展与环境保护双赢，形成了地方与企业协同发展的良好局面。
