The angle of repose and size segregation of iron ore ...

2017-10-1  The size segregation of iron ore granules in the horizontal and vertical directions were investigated both numerically and experimentally. The influence of the sliding and rolling friction coefficients on the angle of repose was first numerically studied. The simulation results show

The angle of repose and size segregation of iron ore ...

We have developed a DEM model to study the packing characteristics of iron ore granules. Two important indices in characterising the packing of granules, i.e. the angle of repose (for packing stability) and a size segregation index, were obtained from the simulations.The comparisons of the simulated and experimental angle of repose and size segregation indices showed good agreement ...
