摘　　要：文章通过MSMPR结晶系统对纯氯化钾及加入2%的氯化镁后的溶液与加入光卤石母液后的溶液进行了氯化钾结晶动力学的研究,计算出了三种情况下氯化钾结晶的基本动力学关系式,分析钠、镁离子对氯化钾结晶过程中成核与生长速率的影响程度,为用光卤石生产氯化钾产品,提高其取得率及增大晶体粒度提供了理论依据。According to using MSMPR crystallization system to study the crystallization kinetics of KCl, the text deduced the basic kinetic equations of KCl crystallization under three cases, and analysed the degree of the effect of Na^2＋ , Mg^2＋ on nucleation and grow speed in the process of KCl crystalhzation. The solution what we study in crystallization kinetics is made of KCl with 2% MgCl2 reacts with carnallitie. The results supply the theoretical base for producing KCl with carnallitite, enhancing the rate of getting KCl and increasing the crystal size.
