  • Flow control valve for continuous discharge centrifugal concentrators
    Patent number: 6796934
    Abstract: Prior continuous discharge centrifugal concentrators for separating higher density particles from a slurry have used pinch valves to control the flow of discharge. Such pinch valves tend to be blocked by coarse particles, requiring shutdown of the machine. The present invention provides a muscle-type valve to provide a circular orifice for the valve bore of continuously variable perimeter.
