我公司化工总厂现有两条过磷酸钙生产线 ,实物产量达 60 0 kt/a。随着市场竞争日趋激烈和农民科学用肥意识的提高 ,需解决过磷酸钙产品的出路。为此 ,1 997年开展了利用过磷酸钙装置生产中低浓度硫基 NPK复合肥的小试研究 ,现将研究结果介绍如下。1 试验原理生产硫基 NPK复合
My company chemical plant existing two superphosphate production lines, the physical output of 60 0 kt / a. With the increasingly fierce market competition and increasing awareness of farmers using scientific fertilizer, to solve the outlet of superphosphate products. To this end, in 1997 to carry out the use of superphosphate plant production of low concentrations of sulfur-based NPK compound fertilizer pilot study, the results are as follows. 1 test principle to produce sulfur-based NPK composite
