angle of repose-wikipedia

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 morphology of the material affects the angle of repose; smooth, rounded

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum

inclinometer for rotary equipment

The benefit of knowing your slope is so that you can create consistent, matched slope between your rollers, bases, and the unit in its entirety on your rotary kiln or dryer. Being aware of your slope can help ward off surprise issues such as unnecessary wear and poor thrust alignment. Industrial Kiln & Dryer Group has created the Inclinometer to measure slope in both vertical and horizontal positions, offering …
