摘　　要：针对饲料级磷酸钙盐装置混合反应造粒机搅拌桨叶片易出现断裂、磨损变短等问题,从桨叶的结构和材质等方面进行优化改进。介绍改造方案和工作原理。改造后,桨叶强度更高,耐磨性和耐折弯性更好,造粒机运行率由82.77%提高到98.50%。Based on the problems that the blades of stirring blades of mixed reaction granulator in feed grade calcium phosphate plant are prone to fracture and wear shorter, the structure and material of the blades are optimized and improved. The transformation scheme and working principle are introduced. After modification, the blade has higher strength, better wear resistance and bending resistance, and the operation rate of granulator is increased from 82.77% to 98.50%.
