Production method for cement clinker by utilizing waste materials from calcium carbide production
The invention relates to a production method for cement clinker by utilizing waste materials from calcium carbide production. The method comprises the following steps: 1) weighing materials: weighing the following raw materials by mass: 30% to 40% of quicklime powder, 30% to 40% of limekiln dust removing powder, 8.5% to 12.5% of shale, 2% to 3.5% of pyrite slag and 11.5% to 15.5% of fly ash; 2) dewatering the quicklime powder and the limekiln dust removing powder; 3) taking the raw materials and carrying out extruding and grinding, and mixing and homogenizing the obtained materials; and 4) carrying out conveying into a kiln, and carrying out calcining according to a novel dry process so as to prepare the cement clinker. The production method provided by the invention uses the quicklime powder and the limekiln dust removing powder in the calcium carbide production process as the raw materials, and employs a novel cement-production dry process which has the advantages of large production capacity, high degree of automation and high thermal efficiency, so secondary utilization of industrial waste materials is realized.
