In this work, the particle dynamics within a rotary granulator will be investigated using a novel measurement technique that allows the tracking of magnetic tracer particles. In particular, the influence of liquid on the dynamics will be investigated, since rotary granulators are often used for the production of agglomerates or for spheronization, where a binder liquid is used in these processes.

The particle dynamics are defined by means of 2D cross-sectional diagrams and distributions of the particle velocities. In addition, models for the evaluation of the particle dynamics are applied and compared. Apart from the influence of the liquid, whereby the influence of the volume ratio and the viscosity is examined, operating parameters of the rotary granulator are varied as well.
