• Online monitoring of particle growth
• Influence of the probe settings
• Interaction between particle stress and granulate size

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 high-shear mixer will be described.

Process monitoring and understanding: the demand for process analysis technologies ascends. This study shows the integration of an inline particle probe and the opportunity to determine the agglomeration process online, so that it is possible to watch the agglomerates grow.Figure optionsDownload as PowerPoint slide
