Cement material prepared from electrolytic manganese residues and preparation method thereof
The invention discloses a cement material prepared from electrolytic manganese residues and a preparation method thereof, and belongs to the technical field of cement environment-friendly materials, and the cement material comprises the following raw materials by weight: 70% of clinker, 10% of limestone, 10% of desulfurized gypsum, 3-5% of coal-fired slag, and 5-7% of electrolytic manganese residues. The method comprises the following steps: sequentially metering and weighing clinker and desulfurized gypsum according to a preset weight percentage; respectively metering and weighing the coal-fired slag, the electrolytic manganese slag and the limestone; the prepared raw materials are fed into a pulverizer for cement grinding, and a cement material is obtained; feeding the prepared cement material into dust collection equipment for dust collection operation; the cement material after dust collection is lifted to the top of a cement storage warehouse and a cement finished product warehouse for storage, so that the technical effects that the content of water-soluble hexavalent chromium in the cement is reduced, the stability is good, the cement is not liable to be oxidized in air to lose efficacy, and the manganese slag is subjected to resource utilization are achieved.
本发明公开了一种利用电解锰渣制得的水泥材料及其制备方法，属于水泥环保材料技术领域，按照重量百分比计，该水泥材料包括以下原料：熟料为70％、石灰石为10％、脱硫石膏为10％、燃煤炉渣为3％～5％、电解锰渣为5％～7％。通过按照预定重量百分比，依次对熟料以及脱硫石膏进行计量称重；分别对燃煤炉渣、电解锰渣以及石灰石进行计量称重；将配置好的原料送入粉磨机中进行水泥粉磨，获得水泥材料；将制得的水泥材料送入收尘设备中进行收尘操作；将收尘后的水泥材料提升至水泥储存库顶、水泥成品库进行储存，达到了降低水泥中的水溶性六价铬含量，且具有良好的稳定性，不易在空气中被氧化而失效，使锰渣获得资源化利用的技术效果。
