Batch crystallization of KCl: the influence of the cooling and mixing rate on the granulometric properties of obtained crystals

The influence of the intensity of mixing (100-500 rpm) and three different cooling rates on crystallization kinetics of KCl and granulometric properties of produced crystals has been investigated on a laboratory scale batch crystallizer. Different process conditions results with different crystal size distribution and crystal shapes. Obtained results show that cooling rate more intensively influences the supersaturation rate, the kinetics curves, and the average crystal size. On the other hand, crystal habit changes more with the intensity of agitation. Crystal size distribution can be expressed by log-normal distribution, i.e. its characteristic parameters, d50 and . Population density of crystal nuclei and overall linear growth rate are evaluated from crystal size distribution. The influence of cooling rate on both parameters (n0, ) is more intense than the influence of mixing rate.
