摘　　要：这一讲主要介绍喷浆造粒转筒干燥制磷铵过程的成粒机理、分析造粒干燥过程的操作条件，以及揭示内返料和无外返料喷浆造粒干燥机的特点。此外还介绍了喷浆流化造粒干燥及喷雾干燥制粉状磷铵流程。This lesson explains the mechanism of granule formation in the spray rotary driergranulator for ammonium phosphate production, and realizes the analysis of operation condition. The specific characterstics of spray rotary driergranulator with internal recycle or entirely without external recycle are expressed. The spray fluidizedbed driergranulator and spraying drier for making powdery ammonium phosphate are also introduced.
