摘　　要：本文通过对包钢选矿厂原磨矿分级作业状况的分析 ,认为该工艺存在流程长 ,设备配置多 ,能耗高 ,旋流器分级效率低的问题。经理论计算和现场试验 ,提出了改进方案并加以实施。主要改进有 :对磨矿流程进行了改进 ,将原三段旋流器分级改为二段 ;重新修订磨矿分级作业工艺参数 ;工艺设备重新配置。改进后 ,在系列原矿处理能力与改进前基本相同的情况下 ,磨矿最终产品细度及稳定性改进前后相当 ,能耗大大降低 ,年创经济效益Some problems as process long, many equipments, high-energy consumption and cyclone efficiency low are found on the analysis of grinding at the Plant. So improvements methods are taken. The three-stage cyclone is changed to two-stage and the parameters are also changed. After upgrade, the fineness and stability of product is same with before, but the energy consumption is much lower and economic benefits can reach above 4,100,000 REM under same rough ore processing amount.
