ABSTRACT:
Fluidized particulate material in an elongated fluidizing bed is separated by means of paddles, on an endless chain running around sprockets, urging at least an upper portion of the fluidized bed towards one end of the bed to enrich that end with lighter particles and the other end with heavier particles. The particles thus separated are removed from the ends of the bed by, for example, flowing over weirs. In one embodiment only the paddles passing along the underside of the chain dip into the fluidized bed while in another embodiment the whole chain and all of the paddles are immersed in the fluidized bed.
