Simulation to quantify the dustiness of powders

T. Londershausen, K. Vaupel*, E. Schmidt, University of Wuppertal, Germany

The dustiness of a disperse solid can be understood as a property, which – when handled in a gaseous environment – behaves similar to an aerosol, releasing the respective particle fraction depending on the given quantity and size distribution. In general, this release of dust is undesirable because it might result in material loss, is often associated with personnel being exposed to it and may cause environmental pollution. The dustiness is therefore a product property, which might change along the process path, for example, through comminution, agglomeration, classification or mixing of the solids involved.

Within the scope of the DFG-focus program 1679 “Dynamic simulation of interlinked solid matter processes”, related property functions will be determined. These property functions describe the dustiness of powders caused by certain types of load and strain..
