the angle of repose. What is the angle of repose? There are two basic angles that describe the flow nature of material. One is the angle of repose (Ar); the other is the angle of surcharge (As). The angle of repose is the angle the material makes with the horizontal when dumped in a pile, such as a stockpile or a stationary belt.

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. ... Calculate conveyor …
