This study applies the discrete element method (DEM) to the roller compaction process for the analysis of particle flow behavior, porosity distribution in the compaction zone and in the final ribbon, as well as the pressure distribution on rollers. The roller compaction setup was implemented utilizing a piston feeder and smooth roller surfaces. The parameters of the elastoplastic DEM contact model were calibrated by uniaxial compression tests, interparticle and wall shear tests. Finally, the simulation results were validated by micro-computed tomography measurements of porosity profiles of manufactured lactose ribbons. From performed studies, it was observed that the particles passing the smallest gap possess higher velocity than the roller surface, and peak pressure is reached before the smallest gap. Furthermore, due to lateral relaxation, the particles in the center of the ribbon are faster than on the walls. The lateral stress can act as a further possible reason for the transversal ribbon splitting.
