Abstract

When a slurry is removed from a crystallizer, classification or non ideal product removal can occur. Classification means that the concentration of particles In the product stream and the average concentration in the crystallizer are different. Recently more information about the classification phenomenon has become available (1–4). It was realized that this phenomenon is very important for the correct Interpretatlonof measured population density curves as well as for the particle size control in industrial crystallizers. Therefore some so-called classification experiments using glass beads and water have been carried out in a 42.5 1 crystallizer. In this paper we present some of our results and discuss the importance of the classification phenomenon.
