Preparation method for producing superfine cement powder by resource utilization of industrial waste residue nickel slag
The invention discloses a preparation method for producing superfine cement powder by resource utilization of industrial waste residue nickel slag. The preparation method comprises the following steps: sieving the waste residue nickel slag discharged by a nickel product production enterprise through a 100-mesh sieve as a raw material, dehydrating the waste residue nickel slag by using dehydration equipment to obtain a 0.5% nickel slag product, feeding 100% by weight of waste residue nickel slag into a grinding machine, and grinding the waste residue nickel slag into a superfine cement powder product; 60-70% of the product is directly used for replacing cement and concrete to prepare products, and the product is widely applied to industrial and civil building engineering construction and the like. The technical indexes of the product quality exceed the technical indexes of cement clinker products, the properties of cement and concrete are improved, the strength, the fluidity ratio, the slump and the like are improved, the utilization rate of the waste nickel slag is improved, a good method is provided for reducing the waste nickel slag, the farmland stacking and landfill cost is reduced, the cement clinker produced from natural limestone, clay and coal is reduced by 80%, the discharge amount of harmful and toxic gas and other components is reduced by 90%, the ecological environment is protected from being polluted and damaged, energy and resources are protected, the production cost is reduced, and remarkable social benefits, environmental benefits and economic benefits are obtained.
本发明公开了一种资源化利用工业废渣镍渣生产超细水泥粉的制备方法，将生产镍产品企业排出的废渣镍渣，通过100目筛为原材料，用脱水设备进行脱水成0.5%的镍渣产品，按重量百分比计为100%废渣镍渣，送进碾磨机粉磨成超细水泥粉产品，直接用60‑70%来替代水泥和混凝土配制产品，广泛用于工业及民用等建筑工程建设。其产品质量技术指标超过了水泥熟料产品技术指标，改善了水泥和混凝土各性能、提高了强度、流动度比，坍落度等性能，提高了废渣镍渣的利用率，为减少废渣镍渣的出路提供一种好的方法，减少了农田堆放填埋费用，减少了天然石灰石、粘土、煤炭生产水泥熟料80%，减少了有害有毒气体等成分排放量90%，保护了生态环境不受污染和破坏，保护了能源和资源，降低了生产成本，取得了显著的社会效益，环境效益和经济效益。
