A system and method for vibration in a centrifuge is disclosed. A centrifuge (10) for removing more dense material from a fluid medium includes a fluid separation wall (26) placed within a non-rotating sleeve (12). The fluid separation wall (26) rotates around the axis of rotation and includes an inner surface and an outer surface with at least one receptacle (30) formed on the inner surface of the fluid separation wall. The receptacle aids in sepration 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 sur face to transport more dense material to the containment zone (18).
