Rules of Thumb: Solids Transfer
The material's angle of repose, typically 30-45°, measures the natural slope of a pile at the top of the bin. There is no direct relationship between the angle of repose and the hopper slope that is necessary to achieve mass flow; the hopper angle must be greater than the angle of repose but testing is required to determine the exact value.
