摘要
在对尿素硫酸复肥生产工艺现状及研究进展分析的基础上 ,利用开阳矿进行了优惠工艺条件选择的实验 ,可得到N -P2 O5为 18.5 -8.5的产品 ,磷矿转化率在 85 %以上 。
Based on the description of situation and proceeding of urea sulfate compound fertilizer,the process indexes were optimized by experiments of Kaiyang ores.The product of N P 2O 5 18.5-8.5 was obtained,in which phosphate ore convertion rate is above 85% and compound fertilizer can be produced in one step.
