摘要： 为了优化梅山铁矿二段磨矿工艺指标，针对二段球磨机磨矿产品中易选粒级产率偏低与细度不达标的问题，开展了钢球级配、介质充填率和磨矿浓度对磨矿效果影响的试验研究。试验结果表明：当ϕ60 mm与ϕ40 mm补加钢球配比为40%∶60%、充填率为42%、磨矿浓度为75%时，可获得优异的磨矿效果；与现场原有方案相比，易选粒级产率和磨矿细度分别提高了16.92，10.66个百分点；合理优化钢球级配、充填率以及磨矿浓度，能够有效改善磨矿产品质量，对选厂优化磨矿工艺指标具有重要的指导意义。

Abstract: In order to optimize the two-stage grinding process index of Meishan Iron Mine，aiming at the problems of low yield and substandard fineness of easy selecting grade in the grinding products of the two-stage ball mill，the experimental study on the influence of steel ball gradation，medium filling rate and grinding concentration on the grinding effect is carried out.The experimental results show that when the ratio of ϕ60 mm and ϕ40 mm replenish steel balls is 40%:60%，the filling rate is 42%，and the grinding concen‐ tration is 75%，excellent grinding effect can be obtained.Compared with the original scheme on site，the yield and grinding fineness of the easy selecting grade are increased by 16.92 and 10.66 percentage points respectively.Reasonable optimization of steel ball grading，filling rate and grinding concentration can effec‐ tively improve the quality of grinding products，and has important guiding significance for optimizing the grinding process index of the concentrator.

Key words: two-stage grinding, steel ball grading, filling rate, grinding concentration
