使用壓力式噴嘴時，罪化是作用在物料上的壓力能轉化為潮液藏動能的結果。壓力作用在噴嘴里的物料上，壓迫物料通過噴嘴上的小孔噴出霧化，壓力式噴嘴既可用于并流模式也可用于噴泉模式，通過改變進料壓力和噴嘴尺寸可以調節粒徑大小。相對其他露化方式，壓力式噴嘴能得到更窄的粒徑分布和更大的顆粒。噴嘴尺寸可根據物料特性和粉末特點來選擇。

When using a pressure nozzle, sin is the result of converting the pressure energy acting on the material into the kinetic energy of the tidal liquid. The pressure acts on the material in the nozzle, and the material is forced to spray and atomize through the small holes on the nozzle. The pressure nozzle can be used in both co-current mode and fountain mode. The particle size can be adjusted by changing the feeding pressure and nozzle size.  Compared with other dew methods, pressure nozzles can obtain narrower particle size distribution and larger particles. Nozzle size can be selected according to material characteristics and powder characteristics.
