A system and method for vibration in a centrifuge is disclosed. A centrifuge
for
removing more dense material from a fluid medium includes a fluid separation wall
placed within a non-rotating sleeve. The fluid separation wall rotates around the
axis of rotation and includes an inner surface and an outer surface with at least
one receptacle formed on the inner surface of the fluid separation wall. The receptacle
aids in separation of more dense material from the fluid medium by forming a void
space between the inner and outer surface. An excitation apparatus associated with
the receptacle to create a vibration within the receptacle. A flow path may extend
through the wall from the void area to the outer surface to transport more dense
material to the containment zone.
