Development of an Apparatus for Measuring Angle of Repose of Granular Materials

This work presents the development of an apparatus for measuring the angle of repose of granular materials. The basic types of angle or repose, the methods of measuring angle of repose of solid, were discussed. The effect of the physical properties of the granular materials on the measured angle of repose to design and construction of bins, hoppers and other storage facilities such as silos were briefly discussed. The angles of repose of twenty different agricultural materials were determined using the developed apparatus.
