Study on Terminal Velocity of Particles in the Teetered Bed Separator

Abstract

Several mathematical models describing particle separation and predict the separations in TBS are available. Because of the complexity of these models, Galvin’s model and Das’s model are of most interest. Equations of Galvin’s model, Das’s model and Alien’s law are used to predict the values of the terminal velocities. Free settling tests of 25 samples were undertaken. The average deviation of Galvin’s model is 0.019043, the values predicted by equations of Galvin’s model are most closes to the experimental data. Therefore, correlation equations of Galvin’s model should be chosen to calculate the terminal velocity of particles in the TBS.
