Method for preparing cement clinker by using copper slag in cooperation with multiple solid wastes
The invention discloses a method for preparing cement clinker by using copper slag cooperating with various solid wastes, which comprises the following steps: mixing limestone and converter slag, crushing and pre-homogenizing, and respectively pre-homogenizing copper slag, volcanic ash and red mud; respectively grinding the pre-homogenized mixture, the copper slag, the volcanic ash and the red mud; the ground raw materials are mixed and homogenized; and carrying out preheating decomposition and clinker firing on the homogenized raw material, and finally rapidly cooling to obtain the cement clinker. According to the method disclosed by the invention, the mixed limestone and converter slag are used for replacing single limestone, copper slag, volcanic ash and red mud are used for replacing iron ore powder and clay and are comprehensively utilized to prepare the cement clinker, so that on one hand, the problem of stockpiling of various solid wastes is solved, resource utilization is realized, on the other hand, the cement manufacturing cost is reduced, and the prepared cement clinker has relatively high strength.
本发明公开了一种利用铜渣协同多种固废制备水泥熟料的方法，包括：将石灰石与转炉渣混合进行破碎并预匀化，分别对铜渣、火山灰和赤泥进行预匀化；将预匀化后的混合物以及铜渣、火山灰和赤泥分别进行粉磨；将粉磨后的原料混合并进行匀化；将匀化后的生料进行预热分解以及熟料烧制过程，最终快速冷却得到水泥熟料。本发明方法使用混合后的石灰石与转炉渣代替单一的石灰石，铜渣、火山灰和赤泥代替铁矿粉与粘土，综合利用制成水泥熟料，一方面解决了多种固废堆存问题，实现资源化利用，另一方面减少水泥制作成本，制得的水泥熟料具有较高的强度。
