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.
