ABSTRACT:
A centrifuge includes a rotational mechanism, a housing, a rotating feed pipe and a basket. The housing includes at least one side and defines an interior volume. The basket is positioned in the interior volume of the housing and is operatively coupled to the rotational mechanism such that rotation of the rotational mechanism is imparted to the basket. The rotating feed pipe extends into the basket through a pipe support positioned over the basket. The rotating feed pipe includes a nozzle operable to direct a flow of liquids, solids or combinations thereof onto a sidewall of the basket. The rotating feed pipe is operable to rotate from a first position towards a second position thereby increasing the distance between the nozzle and the sidewall and varying an angular orientation of the nozzle with respect to a normal to the sidewall.
