介绍一种用尿素生产高氮磷肥的新工艺 ,分析该工艺的技术参数和影响因素。新工艺克服了过磷酸钙和尿素直接相混时会释放出结晶水的局限性 ,所得产品不仅可以作为复肥生产的原料 ,而且可以直接喷浆造粒生产NP复肥 ,因而具有良好的实用性
A new process for producing high N and P fertilizer with urea is introduced, and the technical parameters and influencing factors of the process are analyzed. The new process overcomes the limitation of the crystalline water released when the superphosphate and the urea are mixed directly. The obtained product not only can be used as raw material for the production of the compound fertilizer, but also can be directly sprayed and granulated to produce the NP compound fertilizer, thereby having good practicality Sex
