When it comes to rotating drum dryers, heat transfer is often the first aspect that comes to mind. However, particle mixing, segregation, and the risk of attrition due to mechanical stresses are also critical for achieving a high-quality product. In our recent publication, in collaboration with Hosokawa Micron B.V., we investigated how key design parameters influence these competing aspects, revealing that improving one performance metric can come at the expense of another. Our findings highlight the need for a multi-objective design optimization framework based on the Discrete Element Method (DEM) to balance drying performance with product quality in future work. This work demonstrates how physics-based simulations can explain experimental observations, provide particle-scale insight into the underlying mechanisms, and support the design and optimization of industrial drying processes. https://lnkd.in/eqEjnRKd A big thank you to my co-authors Olukayode Imole, Christian van der Sande, Peter Van Der Wel from Hosokawa Micron B.V. and Balázs Füvesi, Stefan Luding, and Vanessa Magnanimo. #DEM #GranularMaterials #Drying #HeatTransfer #ParticleTechnology #RotatingDrum #Simulation #ProcessEngineering
