A centrifuge with combinations of multiple features is disclosed. In one aspect, a centrifuge for removing more dense material from a fluid medium includes a fluid separation wall placed within a sleeve. The fluid separation wall rotates around the axis of rotation. A receptacle aids in separation of the more dense material from the fluid medium. The receptacle defined in a part by a respective geometry and a respective shape. An opening extends from the void area to the outer surface to transport the more dense material to the containment zone. An excitation apparatus associated with the receptacle creates a vibration within the receptacle. The centrifuge may further include a valve ring including a valve orifice 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 move into the containment zone.

What is claimed is: 1. A method of separating more dense material from a fluid medium in a centrifuge, comprising: rotating a fluid separation wall around an axis of rotation within the centrifuge to produce a centrifugal force that causes the more dense material in the fluid medium to separate from the fluid medium; directing the more dense material along a flow path towards an opening in the fluid separation wall such that the more dense material exits the fluid separation wall via the opening and deposits the more dense material into a containment zone; creating an excitation force within the centrifuge such that the excitation force imparts a vibration on the more dense material; and controlling the flow of the more dense material moving along the flow path. 2. The method of claim 1, further comprising: compressing the separated more dense material in at least one flow path of a receptacle by blocking at least a portion of the at least one flow path with a portion of a valve ring; and moving the valve ring along an outer surface of the fluid separation wall to release the more dense material compressed within the flow path such that the more dense material exits the fluid separation wall. 3. The method of claim 2, wherein moving the valve ring comprises rotating the valve ring along the axis of rotation to align at least one valve orifice with at least one flow path. 4. The method of claim 2, wherein moving the valve ring comprises moving the valve ring generally perpendicular to the axis of rotation such that the portion of the valve ring moves from a first position blocking the flow path to a second position opening the flow path. 5. The method of claim 2, wherein the moving the valve ring comprises sliding the valve ring along an outer portion of the fluid separation wall. 6. The method of claim 2, wherein moving the valve ring further comprises stopping the movement of the valve ring such that the at least one valve orifice aligns with at least one flow path in the stopped position. 7. The method of claim 2, wherein moving the valve ring further comprises stopping the movement of the valve ring at a detent position. 8. The method of claim 2, further comprising returning the valve ring to a default position using a spring biased to the default position. 9. The method of claim 2, further comprising simultaneously aligning all valve orifice with the flow paths along the valve ring. 10. The method of claim 1, wherein controlling the flow further comprises using an intermittent actuator to automatically release the more dense materials to move along the flow path. 11. The method of claim 1, wherein controlling the flow further comprises using an intermittent actuator to automatically release the more dense materials to move along the flow path. 12. A method of separating more dense material from a fluid medium in a centrifuge, comprising: rotating a fluid separation wall around an axis of rotation within the centrifuge to produce a centrifugal force that causes the more dense material in the fluid medium to separate from the fluid medium; directing the more dense material along a flow path through a void area towards an opening in the fluid separation wall such that the more dense material exits the fluid separation wall via the opening and deposits the more dense material into a containment zone; creating an excitation force within the centrifuge such that the excitation force imparts a vibration on the more dense material; controlling the flow of the more dense material moving along the flow path; and releasing more dense material to move along the flow path based on a predetermined condition. 13. The method of claim 12, wherein the predetermined condition compromises a condition selected from the group consisting of a pressure level within the fluid separation wall, a particle characteristic of a clarified fluid stream, or a combination of the pressure level within the fluid separation wall and the particle characteristic of the clarified fluid stream. 14. The method of claim 12, further comprising manually controlling the release of more dense materials to move along the flow path. 15. The method of claim 12, further comprising creating chaos by using an anti-vorticity projection formed within the at least one receptacle to prevent the formation of a cyclonic vorticity. 16. The method of claim 12, further comprising associating an anti-clogging projection with the opening to prevent the more dense material from clogging the opening. 17. The method of claim 12, wherein creating the excitation force comprises generating an ultrasonic vibration. 18. The method of claim 17 further comprising applying the generated ultrasonic vibration to the opening. 19. The method of claim 12, wherein creating the excitation force further compromises generating a vibration frequency greater than approximately 20,000 cycles per second. 20. A method of separating more dense material from a fluid medium in a centrifuge, comprising: rotating a fluid separation wall around an axis of rotation within the centrifuge to produce a centrifugal force that causes the more dense material in the fluid medium to separate from the fluid medium; directing the more dense material along a flow path through a void area towards an opening in the fluid separation wall such that the more dense material exits the fluid separation wall via the opening and deposits the more dense material into a containment zone formed between the centrifuge core and a non-rotating sleeve; creating an excitation force within the centrifuge such that the excitation force imparts a vibration on the more dense material; controlling the flow of the more dense material moving along the flow path; and compacting the more dense material in the receptacle with the aid of the excitation force. 21. The method of claim 20, further comprising partially fluidizing the more dense material using a vibratory device to cause the more dense material to move towards the opening. 22. The method of claim 20, wherein controlling the flow further compromises controlling a removal rate of the more dense fluid with the excitation force. 23. The method of claim 20, further comprising dampening the excitation force with a flexible middle layer such that the excitation force is substantially limited to a receptacle formed in the fluids. 24. The method of claim 20, further comprising creating a motion with the excitation force, wherein the motion is selected from the group consisting of axial, radial, linear, torsional, and arced. 25. The method of claim 20, further comprising creating the excitation force with a frequency in the range of 100 Hertz (Hz) to 40,000 Hz. 26. The method of claim 20, further comprising continuously activating the excitation force during the operation of the centrifuge. 27. The method of claim 20, further comprising activating the excitation force based on operating conditions of the centrifuge to maintain a condition responsive activation. 28. The method of claim 20, further comprising activating the excitation force at periodic intervals to maintain a cyclical excitation force.
