Nov 01, 2010· Importance of Angle of repose and angle of incliantion of drag chain conveyor Dear All, Do you have any information about relation ship between angle of Repose of bulk goods say cement and angle of inclination maximum we can use for transporting it by a Trough chain conveyor.

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative 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 outside angle of the coal pile, as measured on Clean Coal Pile No. 1 after the accident, was between 36 and 37 degrees. This was the angle of repose of the pile. Coal is normally reclaimed by pushing the coal with a bulldozer to chutes located at ground level above the feeders.

Stockpile Calculator . The "Smalis Stockpile Calculator" is simple to use, requires no research on materials and yet, provides the pertinent information regarding all aspects of the stockpile. Simply enter the material to be conveyed and the length of the conveyor that is being considered.

The angle of this slope with respect to the horizontal plane is its angle of repose: j. (Refer Figure ). The Angle of Repose is used as the base value for determining the burden surcharge angle. Angle of surcharge:This is the angle to the horizontal which the surface of the material assumes when the material is at rest on a horizontal ...

PRB coal is extremely friable and will break down into smaller particles virtually independent of how the coal is transported or handled. Once it is exposed by mining, the attrition process of ...

In coal mine subsidence, this angle is assumed to bisect the angle between the vertical and the angle of repose of the material and is 20° for flat seams. For dipping seams, the angle of break increases, being ° from the vertical for a 40° dip. The main break occurs over the seam at an angle from the vertical equal to half the dip.

Angle of repose and surcharge The angle of repose of a material is the acute angle which the surface of a normal, freely formed pile makes to the horizontal. The angle of surcharge of a material is the angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor angle usually is 5

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. Obviously, the drawdown angle will vary depending upon the size range of the material and its wetness.
