摘　　要：通过对给料器、内筒体、中间柱过滤架、溢流槽、外筒体和精矿斗结构的详细设计,建立电磁淘洗精选机改进模型。分析传统精选机和改进精选机的模拟试验,得到分选筒内速度云图和粒子分布图,结果表明改进精选机水流速度分布有利冲散粒子,更有利于提高精矿品位。同时,为精选机的改进研究提供参考。Through the detailed design of the feeder,inner cylinder,intermediate column filter frame,overflow tank,outer cylinder and concentrate bucket,the improved model of the electromagnetic washing separator is established.By analyzing the simulation test of the traditional separator and the improved separator,the velocity cloud diagram and particle distribution diagram in the sorting cylinder are obtained.The results show that improving the water flow velocity distribution of the separator is beneficial to dispersing particles,the improved feeder and intermediate column of the separator are conducive to particle dispersion and better screening of the concentrate.At the same time,it provides reference for the improvement research of the selection machine.
