摘　　要：大红山矿选厂Ⅲ系列磨矿作业为一段闭路磨矿,针对磨矿产品存在粒度特性相对较差的问题,论文经过对比研究分析,发现两段闭路磨矿分级效果较好,改善了磨矿产品的粒级组成,可提高铜资源的回收率。The III series ore grinding operation of Dahongshan concentrator is one-stage closed circuit grinding,because of the grinding products have the problems of relative poor particle size characteristics,we did the comparative study and analysis,we found the two-stage closed circuit grinding has good results,therefore the size fraction composition of grinding product is improved and the recovery rate of copper is increased.

关 键 词：一段闭路磨矿 两段闭路磨矿 粒级组成
