Angle of repose - wartsila

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°. The angles of repose for ores range between 34° for copper from ...

Angle of Repose - an overview ScienceDirect Topics

Angle of repose is another important physical property used for characterization of the bulk of particulate foods such as seeds, grains, flours, grits, and fruits. When granular solids are piled on a flat surface, the sides of the pile are at a definite reproducible angle with the horizontal leveled surface (Fig. 3.8).This angle is called the angle of repose of the material.
