Abstract: The Chinese traditional medicine superfine grading is one of key technology in the production of the Chinese traditional medicine powder. The production method of the Chinese traditional medicine pow der and the major production process of GM superfine vibration grinding milling series was introduced. The principle and using method of the su perfine grading machinery was discussed. According to the question of superfine grading machinery, the tube multi-grade superfine grading ma chinery was analysed, which was suitable for superfine powder grading of the Chinese traditional medicine.
