The Reflux Classifier (RC) is a relatively new technology that is mainly used in the coal and minerals industries. The operating principle of this system is based on three mechanisms: hindered settling, autogenous dense medium and lamella settling. This paper summarizes the experimental work undertaken to assess the RC for the beneficiation of ...
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 …
