    • Abstract
  • 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.
