The angle of repose and size segregation of iron ore

2017-10-1  Furthermore, we also compared the simulated angle of repose of mono-sized iron ore granules with the experimental result when the granule size increased from 5.0 to 9.0 mm. Fig. 12 shows the experimental trend and the simulated ones obtained using the friction coefficient combinations C1–C6. It can be seen that the simulated angles of repose for C2, C4 and C5 are still a better match

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, demonstrating that the developed model is capable of predicting the behaviour of iron ore granules

2014-11-24  The angle of repose of a material is the acute angle which the surface of a normal, freely formed pile makes to the horizontal. The angle of surcharge of a material is the angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor belt.This angle usually is 5 degrees to 15 degrees less than the angle of repose, though in some materials it
