摘要
目的 :针对中药材粉碎特性 ,提出一种“中药材冲击摩擦超细气流粉碎”方法 ,该方法可有效解决现有中药材超细粉碎方法中关于超细粉碎效率的问题 ,特别是现有气流粉碎装置对不同物性的中药材粉碎适用性较差的缺点。方法 :将喷射气流的高速冲击粉碎作用和旋转靶的高速摩擦粉碎作用复合用于中药材的超细气流粉碎中 ,并经分级获得中药材超细粉体。结果 :通过几种典型中药材的超细粉碎实验表明 ,粉碎平均粒径分别为 2～12. 7μm。结论 :该方法具有适用性强、超细粉碎效率高的优点 。
Objective: TO introduce a method of ultrafine grinding by impacting and attriting in jet mill, which can solve effectively about grinding efficiency and suitability for variant Chinese medicinal materials. Method: Raw materials are uniformly distributed to multiple nozzles and accelerating pipes, and high-speed impact on a rotary target with surface of various friction veining, so Chinese medicinal materials are pulverized through recombination action of impaction and attrition, and ultrafine powder are separated by internal classifier. Result: The grinding experiment go to show that average fineness of several kinds of typical Chinese medicinal materials powder are 2.0～12.7 microns. Conclusion: This method has obvious advantage of suitability and efficiency for ultrafine grinding Chinese medicinal materials.
