Abstract
This research evaluates granulator performance at GreenCycl B.V., focusing on particle breakage factors like size and material properties. It uses the discrete element method (DEM) and Tavares' breakage model for simulations. The granulator's geometry is modeled in SolidWorks and imported into EDEM.
Key research question: "How to improve granulating performance at GreenCycl B.V.?" Four geometries (Long Axis - 2 Cutting Blades, Long Axis - 3 Cutting Blades, Short Axis - 2 Cutting Blades, Short Axis - 3 Cutting Blades) are tested, with the Short Axis - 3 Cutting Blades being the most productive.
Further analysis of rotation speed and filling technique shows high rotation speed and simultaneous filling yield the best results, despite higher power consumption. The study provides insights for optimizing granulator performance to maximize productivity and efficiency at GreenCycl B.V.
