Method for synergistically preparing cement clinker from coal-fired furnace slag and coal gangue
The invention relates to the technical field of cement preparation, in particular to a method for preparing cement clinker by using coal-fired furnace slag and coal gangue synergistically. The invention aims to solve the problems of large coal gangue stacking amount, environmental pollution and the like, and utilizes the coal-fired slag to improve the burnability of the raw material, reduce the coal consumption of the clinker and improve the quality of the clinker. The cement clinker is prepared by taking the coal gangue and the coal-fired furnace slag as aluminum-silicon raw materials and adding the limestone and the sulfuric-acid slag in different mass proportions, so that the problem of environmental pollution caused by the coal gangue is solved, the coal consumption of the clinker is reduced, and the cement clinker with excellent performance is produced. The specific preparation method comprises the following steps: 1, crushing coal-fired furnace slag, coal gangue and other raw materials, sieving with a standard sieve, and collecting for later use; 2, mixing the raw materials according to a certain proportion; and 3, calcining the prepared raw material at high temperature to obtain the cement clinker. The method for synergistically preparing the cement clinker from the coal-fired furnace slag and the coal gangue can be obtained.
一种利用燃煤炉渣和煤矸石协同制备水泥熟料的方法，涉及水泥制备技术领域，利用燃煤炉渣和煤矸石制备水泥熟料。本发明的目的是解决煤矸石堆存量大，污染环境等的问题，以及利用燃煤炉渣改善生料易烧性，降低熟料煤耗，提高熟料质量。以煤矸石和燃煤炉渣为铝硅质原料，加入不同质量比例的石灰石和硫酸渣以制备水泥熟料，不仅解决了煤矸石对环境的污染问题，降低了熟料煤耗，而且生产出了性能优异的水泥熟料。具体制备方法：一、将燃煤炉渣和煤矸石等原料经破碎后过标准筛，收集备用；二、将各原料按一定比例配合；三、将配合好的生料经高温煅烧，即可得到水泥熟料。本发明可获得一种以燃煤炉渣和煤矸石协同制备水泥熟料的方法。
