More2017-10-1 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 ...

Angle of repose, as a basic parameter of particle property, defined as the angle between the inclined surface of the pile and the base surface, is known to qualitatively analyze the flow characteristic of granular particles, shown in Figure 3.

More2018-12-6 The angle-of-repose represents the outer angle of the bulk material and can be determined directly after such an experiment. The draw-down angle describes the inner angle after the bulk heap has dispersed from the middle. The mean value along the bulk material was then calculated for both angles and the results were used in the subsequent analyses.

More2014-1-21 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

MoreGlidants which lowered the angle of repose did not necessarily increase the flow rate and marked changes in flow rate were not always detectable by angle of repose measurement. In addition, a comparison of the angle of repose and the flow rate of various commonly used raw materials indicated that the angle of repose was not a reliable method ...
