将当代水泥工业煅烧新技术——窑外预热或预热、预分解技术与石灰石烧结法从高铝粉煤灰中提取氧化铝、残渣生产水泥的已有技术结合，为深化节能改调篦冷机等，使空气重复通过热熟料层升温发电，创新热能利用率；产优质铝氧(非冶金级)可替进口加工；残渣全部烧制高质量水工等水泥可竟销国际，渣因已自粉化、含水泥矿物成份80％，只配＜15％石灰石，从大降料、能得高益，并使水泥节资1/3和根治环境污染。
heat utilization ratio is innovated. High-quality non-metallurgical grade aluminum oxide produced by the invention can substitute the imported products. High-quality hydraulic engineering cement and the like which are sintered by using all residues can be sold in the international market. The Residue is treated by using the self-powdered process and includes 80% of cement mineral components, and only less than 15% of limestone is used, so that the consumption of raw materials is greatly reduced, high yields can be achieved, the cost can be saved by 1/3, and environmental pollution can be completely treated. |
