Abstract
Using a well-mixed type and cone-shaped continuous classified bed-type crystallizer, we studied the effect of classification through a crystallizer and a salt leg without operation, and the influence of the crystallization rate, suspension density, growth rate, and nucleation rate on the crystal size distribution with a common crystallizer. Based on these results, we verified the results of narrowing the crystal size distribution experimentally. To calculate the crystal size distribution of products, we used the cumulative amount obtained using the Rosin-Rammler method for practical use, and investigated the operational conditions for narrowing the crystal size distribution, which was characterized by enlarged n. We also calculated the growth rate and the nucleation rate using Toyokura's design chart.
