Quantification of Particle Shape and Angularity Using the Image Analyzer



The image analyzer commonly used by the powder metallurgists has been successfully employed to quantify angularity and shape characteristics of granular materials. In this paper a detailed procedure has been outlined. Results of investigation of different natural sands are presented in the form of a distribution of tangent count taken as a measure of angularity. Powers' roundness index has been calibrated against the tangent count. Mechanical properties of different sands have been shown to be correlated with angularity.
