This paper applies Drift Flux theory for the first time to explore the relationship between the liquid and solids flow through fluidized beds in the context of desliming of dense minerals. At low solids fluxes the process is not flux curve constrained. Here continuity considerations indicate the net liquid flux through the lower bed is upwards, ideal for the removal of slimes from the underflow product...
The Reflux Classifier (RC) is a fluidized bed separator capable of operating at high hydraulic loadings due to the presence of parallel inclined plates within the system. When the fluidized suspension passes up through the inclined channels formed by the plates, faster settling particles segregate onto the inclined surfaces, and slide back down to the zone below, while slower settling particles pass...
