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 on through. The parallel inclined plates provide for a much higher sedimentation area(Galvin et al., 2005).
The reflux classifier (RC) is an innovative device offering advantages in both particle size classification and density separation. The device consists of fluidized bed sections and sets of parallel inclined plates at different elevations. Each set of plates spans the whole cross-sectional area of fluidized bed sections. The RC, a piece of solid–liquid fluidized bed separation equipment with a large processing capacity, was invented by Australian Professor Galvin in 2002 and was originally used for coal separation. Compared with conventional fluidized bed equipment, the RC was equipped with a parallel inclined plate zone on the upper part of the bed. And compared to RC, TARC (trapezoidal inclined channel agitated reflux classifier) was equipped with a stirring device in the column area(Chen et al., 2023).
When traditional classifiers aren’t enough, advanced technology steps in! The REFLUX Classifier (RC™) is a game-changer for precise fine particle separation. What makes this technology so effective in optimizing mineral recovery from challenging feeds? Share your insights!
