摘　　要：运用粒数平衡方程,在MSMPR结晶器中研究了氟硅酸钾(钠)在湿法磷酸中的结晶动力学,建立了成核速率-晶体生长速率及成核速率-晶体生长速率-悬浮密度的动力学模型。By using population balance equation,the kinetics of potassium(sodium) crystallization was studied in a continuous MSMPR crystallizer.The kinetics model of nucleation rate-growthrate,and nucleation rate-growth rate-suspension density were deduced.
