The Reflux Classifier combines the uniform flow conditions of the liquid fluidized bed and the proven throughput advantage of inclined parallel plates. A reflux action develops as a result of the fluidized particles segregating onto the inclined plates, and returning to the fluidised zone below.

A pilot scale Inverted Reflux Classifier was used to separate cenospheres from fly ash waste, following successful studies at a laboratory scale (Kiani et al., 2014, Kiani et al., 2015). The product grade and the cenosphere recovery responded to changes in the feed split ratio in accordance with the earlier study. The responses to changes in ...
