    Investigation into Bulk Material Parameters for Discrete Element Simulation The knowledge of the behaviour of different bulk materials is important for every Discrete Element Simulation which should be close to reality. To describe the behaviour of bulk materials the various Discrete Element Programs use material specific parameters like friction, rolling friction, cohesion, coefficient of restitution and so on. Usually these parameters are not known for the different bulk materials and they have to be determined experimentally. It is also difficult to create a material database, because the parameters depend on many environmental conditions and it is only possible to get a "snap-shot" of this behaviour. At the Chair of Conveying Technology and Design Methods at the University of Leoben test methods are developed which could be used to measure the most important parameters. Figure1: On site test-rigs for detecting material parameters In addition to laboratory test-rigs on-site rigs are currently tested. On-site rigs are necessary, because it is often difficult to obtain bulk material test samples from foreign countries to the laboratory in Leoben. The paper includes a short introduction into the DEM and an overview of the application of the DEM at the Chair of Conveying Technology and Design Methods. In the second part of the paper various test methods for the required material -parameters for the simulations will be presented.
