In this contribution, the particle dynamics and the granular flow in a lab-scaled rotor granulator system (fluid bed rotor processor) are investigated on the scale of individual particles. The numerical approach is based on a Discrete Element Method (DEM) coupled with three-dimensional Computational Fluid Dynamics (CFD) for the gas phase. In this work a novel non-intrusive particle tracking technique, the Magnetic Particle Tracking (MPT) has been used to study the complex granular flow in rotor granulators. The technique allows a simultaneously and non-intrusivedescription of the translational as well as the rotational movement of a tracer particle in dense granular flow. The focus is on the analysis of the particle rotation behaviour at different process conditions. © 2013 AIP Publishing LLC.
