摘要：The aim of this study was to determine the correlations between the external friction angle of wheat kernels vs. the roughness of the friction plate and the basic physical properties of kernels. The average external friction angle ranged from 17° to 24°, and its value increased with an increase in surface roughness. The analyzed relationship was well described by a logarithmic function. The dimensions, mass, geometric mean diameter, aspect ratio, sphericity index and density of wheat kernels had practically no influence on the angle of external friction, which indicates that wheat kernels cannot be reliably sorted based on their frictional properties.
