ABSTRACT:
In a fluid media gravity separator a concentrator bowl having a side wall and a bottom wall that slopes downwardly and inwardly, said bottom wall being formed with a central concentrate discharge port, a media feed injector having a passage with a discharge opening to direct fluid passed therethrough at a high velocity in a spiral path of decreasing radius over the bottom of said bowl that terminates at said discharge port, a splitter in said bowl at said discharge port with a splitting edge in spaced relation to the edge of said discharge port to divide material flowing over said bottom of said concentrating bowl in a spiral path as aforesaid into a portion that flows through said discharge port of said concentrating bowl and a portion that flows upwardly of the central portion of said concentrating bowl, a vortex tube in said concentrating bowl overlying said splitter with its input end overlying said splitter to receive the portion of material split by said splitter that is directed upwardly in said bowl, said vortex tube having a discharge outlet for materials directed thereinto as aforesaid, the improvement of a rotatable mounting means for said splitter to permit said splitter to rotate about the vertical axis of said bowl in use, said splitter being rotatably mounted on its mounting means, and means for rotating said splitter in use.
