Grain Angle of Repose

Oct.31, 2017Keywords:Grain Angle of Repose, Silo Hopper, Silo Net Volume

Grain is a kind of scattering material ,the cohesion of grain is small, the grain seeds form grain pile in free falling, due to the mobility and gravity of grain seeds, the grain seeds will form a cone, this nature is named as food scattered.

The scattering of food is usually expressed in angle of repose, the angle of repose means that the intersection angle between the cone slope and bottom horizontal line formed by nature. The angle of repose is inversely proportional to the scattering property, that is, the scattering is good, the stationary angle is small; The scattering is poor, and the angle repose is large.
