The models of mass transfer and crystal growth rate in cycling-fluidized crystallization were simulated by means of the theory of Whiteman’s mass transfer film.The experiment results show that within the some conditions

the crystal growth rate in cycling-fluidized crystallization is only related with the physical and chemical properties

the super-saturation level and the diameter of crystal seeds in crystal system

which regularity is that the crystal growth rate is in direct proportion to the diffusivity of solutes

the diameter of crystal seeds

the relative density between solution and the solute and the super-saturation level

and in inverse proportion to the viscosity of solution

the density of crystal

so with them the crystal growth rate in cycling-fluidized crystallization can be easily predicted among wide flow speed ranges by the models.
