摘要: 为了优化磨矿分级作业,充分挖掘磨机潜力,降低磨矿消耗,实现企业的可持续发展,对太钢尖山铁矿选矿厂一段磨机适宜介质配比开展了系统研究。结果表明:一段磨机[?]120 mm、[?]110 mm、[?]80 mm和[?]60 mm磨矿介质质量配比以35%∶25%∶20%∶20%为佳;锻球的磨矿效果优于铸球;相对于现场生产指标,无论是以原矿计的磨机利用系数还是以新生成-0.074 mm粒级计的磨机利用系数,一段磨矿介质优化后均高4%以上,达到了预期目标。

Abstract: A systematic study was carried out on the suitable medium ratio of the primary mill in Jianshan Iron Mine of TISCO for optimizing the grinding-classification operation, fully tapping the potential of mill, reducing the grinding consumption, and realizing sustainable development of the enterprise. The results indicated that it got the best grinding effect for primary mill when the medium mass ratio was 35%∶25%∶20%∶20% corresponding to the ball diameter of [?]120 mm, [?]110 mm, [?]80 mm, and [?]60 mm. The grinding effect of forging ball was better than that of casting ball. Compared with field data, the utilization coefficient of mill either for raw material or for new generation of -0.074 mm was increased more than 4%. The expected target was fulfilled.
