Production method of carbide slag cement
The invention provides a production method of carbide slag cement, and belongs to the technical field of cement production, and the production method comprises the following steps: taking sandstone, iron ore and slag for burdening, feeding into a roller press for grinding, mixing the obtained discharged material with fly ash, and sorting to obtain an auxiliary material finished product; mixing the carbide slag and the auxiliary material finished product, and homogenizing in a raw material homogenizing silo; sequentially preheating and pre-decomposing the homogenized raw material, feeding into a rotary kiln for calcining to obtain clinker, feeding the clinker into a grate cooler for cooling, and feeding into a clinker warehouse for storage for later use; the clinker, the desulfurized gypsum, the slag and the fly ash are mixed and then fed into a combined grinding system to be ground, and a cement finished product is obtained. The method is used for solving the problems of consumption of a large amount of native natural resources in cement production, treatment of carbide slag and other solid wastes and pollution; according to the method, calcium carbide slag is used for replacing limestone to produce cement, the quality of a cement finished product is stable, the consumption of native resources is remarkably reduced, industrial solid waste is recycled, and the production cost is reduced.
本发明提供一种电石渣水泥的生产方法，属于水泥生产技术领域，包括：取砂岩、铁矿石、炉渣配料后，送入辊压机进行粉磨，并将所得出料与粉煤灰混合后进行分选，得到辅料成品；取电石渣和辅料成品混合后，送入生料均化库内进行均化；将均化后的生料依次经过预热、预分解后，送入回转窑进行煅烧处理得到熟料，将熟料送入篦冷机冷却后，送入熟料库储存备用；将熟料、脱硫石膏、炉渣和粉煤灰配料后，送入联合粉磨系统中进行粉磨，即得水泥成品。本发明用以解决水泥生产消耗大量原生自然资源、电石渣等固废的处理及污染问题；该方法以电石渣替代石灰石生产水泥，水泥成品质量稳定，对原生资源消耗量显著降低，将工业固废再利用，降低生产成本。
