Angle of repose. The angle between the horizontal line and the side of the cone formed when the granular materials as grain, coal, sand or ores are poured onto a flat surface. The angle of repose of most grain loads ranges between 20° and 22°, but for barley it reaches 46°.

STEP 2 - Calculate the hopper angle for mass flow. It is usually desirable to have a mass flow happening in silos or hoppers. Jenicke has tabulated, for different wall friction angle and internal friction angle the maximum hopper angle for which we can get a mass flow. It is 1st necessary to
Pellet count (number of pellets per gram) 3. Bulk density gradient due to compaction 4. The angle of repose (37°) is not considered. This angle changes from converse to inverse as pellets are removed from the bottom of the silo. 5. The cone angle may not be 45° in all silos. Formulas: Volume of a cylinder = height x 0.7854 x diameter²
Pellet count (number of pellets per gram); 3. Bulk density gradient due to compaction; 4. oThe angle of repose (37 ) is not considered 5. In order to simplify the calculations, the cone angle is assumed to be 45o. This may not be true in all silos. (Note that the height of a 45o degree cone is generally half of the cylinder diameter) Formulas:
