- A model is presented which relates the crystal size distribution (CSD) from a mixed-suspension, mixed-product-removal (MSMPR) crystallizer to the distribution of growth rates. This model is based on the assumption that individual contact nuclei have some inherent growth rate which remains constant, but the growth rate may vary from crystal to crystal. The crystal size distribution can be calculated from prior knowledge of the growth rate distribution. A limited knowledge of only the coefficient of variation and the mean growth rate permits an approximation of the expected crystal size distribution. Conversely, estimates of the mean and variance of the growth rate distribution can be determined from the moments of the CSD from an MSMPR crystallizer

- Based on experimental results, it is concluded that potash alum contact nuclei grow at a size-independent rate in a system where flow does not result in crystal collisions. Both initial size and growth rate distributions are present for contact nuclei of potash alum. Curvature in semilogarithmic population density-size plots from continuous potash alum crystallization studies may be due to growth rate dispersion and not size-dependent growth.

- Both initial size and growth rate distributions are observed for contact nuclei of sucrose. Results presented indicate sucrose contact nuclei appear to grow at a size independent rate and that the proper method of analysis of the growth rate dispersion present is the 'constant crystal growth' (CCG) model. Curvature in semilogarithmic population density-size plots from continuous sucrose crystallization studies is probably due to growth rate dispersion and not size dependent growth.
