摘　　要：以0~0.3 mm铁粗精矿作磨矿样品,对其磨矿产品进行了磨矿动力学和箱线图求解,对比分析了陶瓷球和钢锻研磨不同粒级给矿产品下磨矿速度与产品粒度分布特征区别。磨矿动力学结果表明,陶瓷球的磨细能力比钢锻强,且随着时间的延长,磨细能力越发显著增强。箱线图结果表明,随着磨矿时间的延长,陶瓷球磨矿产品中0.010~0.074 mm粒级产率变化比较集中,而钢锻的粒级产率变化比较离散,磨矿产品不同粒级物料产率增加没有陶瓷球磨矿产品均匀。The grinding kinetics and boxplot were solved by using 0~0.3 mm iron concentrate as grinding samples,and the difference between grinding speed and product size distribution characteristics under different particle sizes of ceramic ball and steel forging grinding were compared and analyzed.The grinding dynamics results showed that the grinding ability of ceramic ball was stronger than that of steel forging,and the grinding ability increased significantly over time.Boxplot results showed that with the increase of grinding time,the change of 0.010~0.074 mm particle size yield in ceramic ball milling products was more concentrated,while the change of steel forging particle size yield is more discrete,and the increase of different particle size material yield of grinding products was not as uniform as that of ceramic ball milling products.
