摘要
为研究碾混机在混药过程中的安全性,通过分析碾混机结构,调节进料速度、刮板角度和碾混机转速来进行生产极限的试验,观察混药过程中堵料情况,测试混药后炸药爆速,分析和讨论碾混机混药过程的安全性。研究结果表明,当碾混机转速为22.8 r·min-1,进料速度为4 t·h-1,刮板角度为24°条件下,碾混机运行具有较高的安全性,混药后膨化硝铵炸药的爆速也有明显提高。
The structure of grinding and mixing machine was studied for the security perspective.The production limit experiment was carried out.Plugging material conditions and the detonation velocity of explosive were observed via adjusting operation parameters： feeding speed,scraper angle,grinding and mixing machine speed.The safety of the grinding and mixing machine was analyzed and discussed.Results show that when the speed of the grinding and mixing machine is 22.8 r·min-1,the feeding speed 4 t·h-1,the scraper angle 24°.
