Abstract

The fluidization behavior of non-magnetic cohesive particles in a magnetic fluidized bed was investigated. In order to determine the influence of coarse magnetic powder amount on the fluidization characteristics of non-magnetic cohesive powders, the minimum fluidization velocity and pressure drop were measured. The experimental results showed that the minimum fluidization velocity decreases significantly by adding coarse magnetic powders in the magnetic fluidized bed of non-magnetic cohesive particles since coarse magnetic powders can break up the plug and channel. Moreover, the minimum fluidization velocity of cohesive particles decreases with increasing the amount of coarse magnetic powders, but there is no any change for the minimum fluidization velocity after the amount of coarse magnetic powders is in excess of 40%.
