介绍“干法”硝尿磷肥的生产工艺，该工艺简单、流程短、能耗低、无三废，可利用中低品位磷矿，一次性加工得到复合肥，且有效成分可调，是一种与传统磷肥工艺完全不同的、且不需硫作原料的磷肥生产新工艺，亦可用于硝酸磷肥的技改。 This paper introduces the production process of “dry process” nitrification and phosphate fertilizer, which has the advantages of simple process, short process, low energy consumption, no waste and low-grade phosphate rock, one-time processing to obtain compound fertilizer and adjustable active ingredient With the traditional phosphate fertilizer technology completely different, and do not need sulfur as raw materials for the production of new phosphate fertilizer technology can also be used for technological transformation of nitrophosphate.
