A modelling of a continuous fluidized-bed crystallizer is developed. The model is based on the description of the fltidized bed as a multistage crystallizer, in order to take into account the segregation and particles mixing within the bed. This model is compared to experimental data obtained during

✦ Synopsis
The crystallization of sodium perborate tetrahydrate (SPT) was carried out in a batch crystallizer with and without seeding. SPT concentration and CSD were monitored as functions of time, and the final crystals visualized by SEM micrography. Experimental evidence for primary and secondary nucleation, crystal growth and crystal agglomeration was observed. Thus, a simulation model including these processes is presented. From the experimental data, seven parameters of the model were fitted by optimization in two different steps.

## Abstract In the present work the examination of the proposed earlier model of spontaneous crystallization process was done. The model describes kinetics of the crystallization process after the end of the induction period. To test the model the published data on crystallization and aggregation k
