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.
