摘　　要：为了能够安全高效生产黑火药,在阐述黑火药制备过程的基础上,提出一种圆筒混合机制备黑火药方案。建立药剂受力模型和运动计算模型,分析药剂在滚筒不同转速下的受力情况与运动规律,得到了药剂的运动方程和落点速度,并采用安全性监测系统进行远程监控。结果表明:该方案能实现对烟火药的粉碎与混合操作,以及人机隔离和无人化生产,达到了预期的设计要求。In order to produce black powder safely and efficient,the process of preparation and production of black powder was described.A preparation project of black powder using drum mixer was proposed,and crushing and mixing black powder were achieved.The forced model and movement model were established,the forced feature and movement method of black powder in drum mixer which was under different rolling speeds analyzed,equations of motion and placement speed obtained,and safety monitoring system was adopted to monitor remotely.Man-machine isolation and unmanned production were realized,and the desired design requirement was achieved.
