| Abstract: | The necessity of concentrated-urea spraying granulation process for NPK is examined,several processes are compared in technological features,including imported overseas processes(by TVA,K-T,Hydro,Incro etc),domestic processes(by improved ammonia acid process,improved TVA process in Taiwan,ammonium sulfate pipe reactor process,drum-ammonization sulfate-based NPK process etc),delivering a reference to NPK producers adopting urea-based slurry-spraying granulation or steam granulation processes. |

| Keywords: | urea-based NPK slurry-spraying granulation technological feature |
