摘要
介绍了目前国内生产粉状磷铵的主要工艺流程 ,并详细比较了用于“中和料浆浓缩法磷铵工艺”的 2种粉状磷铵工艺流程的各项技术经济指标 。
The main domestic process flow is deseiibed for the production of powdery ammonium phosphate at present, a detailed comparison is given of the two powdery ammonium phosphate process flows used in the ammonium phosphate process by concentration of the neutralized slurrv in terms of various techno-ecnomic indications,and the process flow for the manufacture of powdery ammonium phosphate by fluid-bed counter-current sprav drying is recommended.
