An Experimental Investigation on Segregation Process of Binary Materials Based on Various Vibration Conditions

Abstract


The mixing and segregation process of binary steel-glass mixture within a vertically vibrated containerat different frequencies are investigated in this paper. The image processing techniques areemployed to track the convection flow of granular materials.Six different amounts of frequency (20, 25, 30, 35, 40, and50 Hz) for certain amplitudes are used to study the effects of miscellaneous vibration conditions on the velocity fields of moving beads.The results show that increasing frequency with constant amplitude has a positive effect on increasing the velocity movement of the beads in addition, the decreasing of amplitude at almost constant dimensionless vibrational acceleration cause the velocity movement of the beads to be increased.The granular bed was divided into three horizontal parts and a separate study was provided for each one.
