摘　　要：张庄铁矿为了降低磨矿作业能耗及改善产品粒度分布特性,针对二段磨矿分别进行了钢球精确化磨矿和陶瓷球替换钢球磨矿优化试验。试验结果表明:2种优化方式的磨细能力都与原钢球磨矿效果接近,且都可降低磨矿能耗,改善产品粒度组成;2种优化方式在工业上的应用方式和效果均不一样,钢球精确化磨矿的应用更简单,但节能降耗效果较弱;陶瓷球替换钢球磨矿的应用更复杂,磨矿效果易受分级设备性能限制,但节能降耗效果显著,且陶瓷球磨矿工艺稳定,是铁矿山细磨段提高磨矿效率及降低磨矿成本的有效方式。In order to reduce the energy consumption of grinding operation and improve the particle size distribution characteristics of products in Zhangzhuang Iron Mine,the optimization tests of steel ball precision grinding and ceramic ball replacement steel ball grinding are carried out for the second stage grind-ing.The test results show that the grinding capacity of the two optimization methods is close to the grinding effect of the original steel ball,and both of them can reduce the grinding energy consumption and improve the particle size composition of the product.The application methods and effects of the two optimization methods in industry are different.The application of steel ball precision grinding is simpler,but the effect of energy saving and consumption reduction is weak.The application of ceramic ball instead of steel ball grind-ing is more complicated,and the grinding effect is easily limited by the performance of classification equip-ment,but the energy saving and consumption reduction effect is remarkable,and the ceramic ball grinding process is stable,which is an effective way to improve the grinding efficiency and reduce the grinding cost in the fine grinding section of iron mine.
