| Abstract: | On the basis of analyzing the nucleation and crystallization theory of carnallitite and KCl in the process of producing KCl,in addition,combining the producing actuality,we put forward a new theory of utilizing TDB crystallization technic to produce carnallitite and using speed control crystallization technic to produce quality KCl,and conduct the technical research.The result shows that the particle size of KCl produced by the new technic is more than 0.45mm,and the content of dry basis KCl is not less than 98%. |
