Enhanced gravity separation device using closely spaced channels

An enhanced gravity separation device comprising a plurality of vessels having outer and inner regions, radiating from and rotatable by a central shaft, a feeder for introducing a feed of mixed denser and less dense fluid matter into the outer regions of the vessels, an array of closely spaced inclined plates positioned within each vessel between the outer and inner regions such that overflow of less dense matter from the array reports to the inner region and underflow of denser matter reports to the outer region, the inclined plates being inclined relative to the central shaft, an underflow removal device for removing the underflow from the enhanced gravity separation device and an overflow removal device for removing the overflow from the enhanced gravity separation device, wherein the underflow and overflow removal devices are operable to remove the underflow and overflow, respectively, while the vessels are being rotated by the central shaft, and wherein said feeder comprises conduits each having a feeder outlet configured to introduce a fluidization fluid into of the outer regions of the vessels causing a fluidized bed to form in these outer regions directed towards said inclined plates, said feeder outlets each being located at a distal end of each outer region.
