Abstract:
1. A centrifuge for removing more dense material from a fluid medium, comprising: a fluid separation wall placed within a sleeve to form a containment zone therebetween; the containment zone operable to receive a portion of the fluid medium having a greater concentration of the more dense material; the fluid separation wall aligned generally parallel to an axis of rotation and operable to rotate relative to the axis of rotation; at least one receptacle forming a part of the fluid separation wall such that the at least one receptacle includes a void area; the at least one receptacle operable to aid in separation of the more dense material from the fluid medium; at least one opening extending through the fluid separation wall from the void area to the outer surface of the receptacle; the at least one opening operable to transport the more dense material to the containment zone; a valve ring forming a part of the fluid separation wall, the valve ring including at least one valve orifice formed in the valve ring; and the valve ring having a first position which blocks the more dense material from exiting the receptacle and a second position that allows the more dense material to exit the fluid separation wall and move into the containment zone.
