    Performance of the reflux classifier for gravity

    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.
