研究了棒磨机和球磨机的某些磨矿参数在干式间歇粗粒磨矿时对磨矿产品细度和磨机能耗的影响。正弦抛物线方程适于描述粒度的分布情况。方程的常数与磨矿参数有关。对这些参数可作数学上的分析。此时,还建立了磨机能耗与磨矿参数之间的关系, The effects of some grinding parameters of rod mill and ball mill on the fineness of grinding products and the energy consumption of the mill during the dry intermittent coarse grinding were studied. The sine parabolic equation is suitable for describing the distribution of particle size. The constant of the equation is related to the grinding parameters. These parameters can be used for mathematical analysis. At this time, also established the mill energy consumption and the relationship between grinding parameters,
