选用三种不同密度的研磨球，采用物理研磨法制备了球形超细CL-20颗粒，介绍了研磨细化装置的工作原理，分析了研磨球密度和研磨时间对超细CL-20的平均粒度、粒度分布和球形度的影响；并对球形超细CL-20的性能进行了测试。结果表明，采用低密度球研磨所得超细CL-20呈类球形，机械感度显著降低，热稳定性优于原料CL-20，研磨前后CL-20同为ε-型，晶型保持不变；高密度研磨球仅对物料细化作用明显，低密度研磨球细化物料的同时对物料圆滑效果良好，所得球形度可达0．9，粒度均匀，分布集中。

The spherical superfine CL-20 were prepared using a physical grinding machine with three kinds of grinding balls, and the mechanism of the machine was introduced.The effects of the density of grinding balls and grinding time on the physical structures such as average particle size, particle size distribution and roundness and mechanical sensitivity of superfine CL-20 were studied.Results show the superfine CL-20 particles obtained with low-density grinding balls are spherical, and its mechanical sensitivity is significantly reduced, and its thermal stability is better than raw CL-20, and the polymorph remainsε-type.The high-density grinding balls can refine the materials well, while the smoothing effect of low-density grinding balls is better, and the particle-size distribution of superfine CL-20 is uniform and concentrated with roundness up to 0.9.
