Flow Properties Testing

Frictional measurements between wear liners and the bulk material provide the design basis for transfer chutes and hoppers. From wall friction charts, minimum chute and valley angles may be related to the material bed depth. Adhesion and wall friction on large (lump) materials can also be measured in a rotating style wall friction tester.

The simulation results show that the angle of repose of iron ore granules was greatly influenced by granule size, sliding and rolling friction coefficients. A decrease in granule size or an increase in either the sliding or rolling friction coefficients significantly increased the kinetic energy dissipation rate of the discharged granules during the packing process.
