This paper deals with agglomeration processes in a high-shear mixer and the integration of an inline particle probe. The purpose is to determine particle size distribution continuously in real-time. High-shear mixers rotate with a very high mixing tool speed. As a result, not only a mixing effect, but also a granulating effect (under certain conditions) is obtained. This granulating effect is to be studied extensively using an inline particle probe. In the first instance, it is decisive to integrate the probe and find settings to measure and to represent the whole particle size distribution in the mixing vessel. This article will highlight some of the findings obtained from the comprehensive parameter study. Additionally, the technical implementation of the inline particle probe in a highshear mixer will be described. (C) 2014 Elsevier B.V. All rights reserved.
