Angle of Repose and Handling Dry Bulk Solids

Angle of repose is the angle above a horizontal plane at which a material will naturally rest. When agitated by a rumbling belt conveyor, for example, this angle is significantly but predictably reduced. The dynamic angle of repose, or angle of surcharge, plays a large part in …

Angle of repose - Wikipedia

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. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.
