The breakage of Al2O3 agglomerates is investigated by compression tests. For the L-threonine crystals single particle impacts with a wall are performed. In order to obtain reproducible results an electromagnetic particle gun has been designed. The experimental results are then used to derive a discrete element model to analyze the microdynamics and breakage mechanisms of needle-shaped particles. A good qualitative agreement between simulations and tests is achieved.en0032-591020111-28898ElsevierAgglomeratesBreakage behaviourDiscrete element modellingL-threonine crystalsScienceJournal Article10.1016/j.powtec.2010.02.025Journal Article
