Process for producing cement by using lithium slag as cement admixture to replace part of water granulated slag
The invention relates to the technical field of industrial waste residue utilization and cement building materials, and discloses a process for producing cement by using lithium slag as a cement admixture to replace a part of water granulated slag, which comprises the following operation steps: crushing and conveying coal gangue and limestone, stacking and conveying desulfurized gypsum, water granulated slag and lithium slag, proportioning, grinding cement and the like. The water content in the lithium slag is strictly controlled; normal blanking is maintained, so that a production line systemoperates stably after replacement, the produced cement performance meets related standards, the quality is stable, the cost is saved, industrial waste residues of a lithium power plant can be utilized, the environmental protection pressure is reduced, good economic and social benefits are brought after utilization, and sustainable development of industry, resources and environment is facilitated.
本发明涉及工业废渣利用及水泥建材技术领域，公开了一种锂渣替代部分水渣作水泥混合材生产水泥工艺，包括以下操作步骤：煤矸石、石灰石破碎及输送，脱硫石膏、水渣、锂渣堆棚及输送，配料及水泥粉磨等工艺。本发明通过严格把控锂渣内含水量，保持正常下料，从而达到替换后生产线系统运行稳定，生产的水泥性能符合相关标准，质量稳定，并节约了成本同时可消化锂电厂的工业废渣，减轻环保压力，消化后带来良好的经济和社会效益，利于工业、资源环境的可持续发展。
