Abstract
The sieved sizes of granular materials were graded by using the vibratile-sizer. The physical characteristics, the angle of internal friction, the angle of wall friction and the angle of repose of granular material were measured. The effects of the shape and size of granular materials on the angle of internal frication, the angle of wall friction and the angle of repose of granular material were evaluated. An experiment by means of tracer particles on particles flow lines and isochronal lines under gravitational field in cylinder storage was carried out. The relationship between the particles flow and the diameter of the exit and the effects of the height of the particles in storage on the particles flow were studied. The influences of the physical characteristics to the flow characteristic of granular materials were analyzed. The results can serve as the experiment basis for the structure design of bulk solid storage and conveying equipments.
