镁磷比m(MgO)/m(P2O5)>8%的高(含)镁磷矿在硫酸法磷肥生产中,含镁磷酸盐会严重影响反应过程,导致产品理化性能变差,特别是产品含水很高,而且极难挥发,潮湿易结块,造成包装贮运和施用困难。阐述应用高镁磷矿生产过磷酸钙的意义,利用高镁磷矿维持过磷酸钙生产及产品质量的工艺措施和取得的效果。
Magnesium Phosphates with Magnesium Phosphate Ratio m (MgO) / m (P2O5)> 8% In the production of sulfuric acid phosphate fertilizer, magnesium phosphate may seriously affect the reaction process, resulting in poor physical and chemical properties of the product, especially the product High water content, but also extremely volatile, easy to agglomerate moisture, resulting in packaging storage and application difficulties. The application of high magnesium phosphate rock production of superphosphate significance, the use of high magnesium phosphate to maintain the production of superphosphate and product quality process measures and the results achieved.
