摘要分析了T公司用于制备钢铁渣粉的工业废渣的理化性能并针对G95钢铁渣粉试生产阶段闭路粉磨系统存在的问题提出了优化改进方案，调整了管磨机各仓的有效长度及筛分隔仓板的参数，优化了二仓与三仓研磨体级配。技术改进后，系统磨细能力显著提高，出磨钢铁渣粉比表面积由168m2/kg增加至296m2/kg，系统产量由35.6t/h提高至44.4t/h，每天可增加钢铁渣粉产量210t左右，按100元/t钢铁渣粉计算，每月可增效63万元。

Abstract:

The physical and chemical properties of industrial waste slag used for preparing iron and steel slag powder in T Company were analyzed. In view of the problems existing in the closed-circuit grinding system of G95 steel slag powder pilot production stage, the effective length of each bin of tube mill and the parameters of screen separation bin plate were adjusted, and the grinding body grading of the second and third bins were optimized. After the technical improvement, the grinding capacity of the system is significantly improved. The specific surface area of steel slag powder is increased from 168m2 / kg to 296m2 / kg, and the system output is increased from 35.6t/h to 44.4t/h. The output of iron and steel slag powder can be increased by about 210t each day. Calculated based on the cost of steel slag powder is 100 CNY / t, the economic benefit can be increased by 630,000 CNY per month.

Key words: steel slag powder physical and chemical properties closed circuit grinding dynamic grinding
