Powder raw material melting accelerant and preparation method thereof
The invention discloses a powder melting accelerant and a preparation method thereof, and relates to the technical field of cement clinker calcination, the powder melting accelerant comprises 40-70% of activated electrolytic aluminum solid waste, 5-20% of co-doped nano rare earth component, 10-35% of calcination fluxing component, and 5-20% of auxiliary decomposition promoting component. The powder raw material melting accelerant provided by the invention can realize comprehensive recycling of electrolytic aluminum overhaul slag in cement production. The composite raw material melting accelerant provided by the invention has good comprehensive effects of promoting carbonate decomposition, reducing the decomposition temperature of calcium carbonate, improving the burnability of clinker, reducing the calcination energy consumption of cement clinker and improving the quality of the cement clinker.
本发明公开了一种粉体熔解促进剂及其制备方法，涉及水泥熟料煅烧技术领域，所述粉体熔解促进剂含有活化电解铝固体废弃物40‑70％、共掺杂纳米稀土组分5‑20％、煅烧助熔组分10‑35％、辅助促分解组分5‑20％。本公开提供的粉体生料熔解促进剂能够实现电解铝大修渣在水泥生产中的全方位回收利用。本公开提供的复合生料熔解促进剂具有良好的促进碳酸盐分解，降低碳酸钙分解温度，改善熟料的易烧性，降低水泥熟料煅烧能耗，提高水泥熟料质量的综合效果。
