The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or diprelative 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°. The morphology of the material affects the angle of repose; smooth, rounded sand grains cannot be piled as steeply as can rough, interlocking sands. The angle of repose can also be affected by additions of solvget price

A review on the angle of repose of granular materials

Gravel (crushed stone) 45° Metcalf investigated the relationship between the internal friction angle and the angle of repose of crushed rocks on the basis of physical experiments. He concluded that the angle of repose, in general, is not equal to the angle of internal friction of the heaped material but is the angle of internal frictionget price

Crushed Stone Lehigh Hanson, Inc.

Limestone, dolomite and granite are the most common types of rock processed into crushed stone. Limestone and dolomite account for 71% all crushed stone; granite makes up 15%. The remainder is sandstone, quartzite and other types of rock. It is produced by crushing quarried rock, then screening it to sizes appropriate for the intended use.get price

This drawdown angle varies from material to material but is usually about ten degrees steeper than the angle of repose for the material. In other words, if the angle of repose is 38 degrees, the drawdown angle is usually about 48 degrees.
