摘　　要：喷浆造粒干燥机的设计是一个系统工程,不仅与系统内部有关,而且还与供热系统和尾气处理系统有关。分析了喷浆造粒干燥机内的热交换情况,总结了其应用于磷复肥生产装置上的工艺设计要素,包括料幕密度与筒体最佳旋转速度、填充系数和抄板以及热风的引入及分布等。The design of spherodizing dryer is a system engineering, it is related not only to system internals, but also is related to heating system and off-gas treatment system. The heat exchange condition inside spherodizing dryer is analyzed, and the process design factors, including material screen density and the best rotation speed of cylinder, filling coefficient and shovelling plate and introduction and distribution of hot air, of the dryer used for phosphate and compound fertilizer production plant are summarized.
