摘　　要：利用行星式球磨机对药用三七进行超微粉碎试验,就不同的球料比、转速、球磨时间对三七粉体粒径大小的影响进行了研究,并对粉碎前后粉末的粒度分布及微观形貌进行了表征.结果表明,球料比在m(研磨球)∶m(三七)=10∶1,转速500 r/min,时间90 min时得到的三七粉末粒度均匀,平均粒径11.992μm.电子显微镜观察到大片破裂细胞碎片,无大颗粒团块,表明单细胞充分破壁.Experiment result of superfine pulverization of medicinal notoginseng by ball milling was investi -gated in this paper .The effects of different parameters such as ball material ratios , rotation speed and ball milling time on particle size of notoginseng powder were studied .The particle distribution and microscopic morphology were also examined .The results showed that the particle size of notoginseng was uniform and the average size was 11.992μm under the ball material ratio of 10 to 1, the rotation speed of 500 r/min and the milling time of 90 min.Large rupture of cellular debris and no clumps of particles could be ob-served , under electron microscope , which indicated that the single cells were fully broken .
