摘　　要：介绍了包钢选矿厂通过对外购铁精矿再磨再选原料水力输送 ,扩大生产能力的改造 ,外购铁精矿处理能力由 170t/h左右提高到 2 4 0t/h左右 ,外购再磨铁精矿量占综合铁精矿量的 30 % ,综合精矿品位达到了6 4 5 %以上 ,而且改善环境 ,降低运输成本。The transformation of the material transportation and the production capacity for the regrinding and reconcentration of purchased iron concentrate of Bao Steel's concentrator is described. Through the transformation, the capacity for purchased iron concentrate treatment was raised to about 240 t/h from 170 t/h. The purchased concentrate reground amounted to 30% of the comprehensive iron concentrate, whose grade was over 64.5%. Meanwhile, the environment was improved and the transportation cost reduced.
