Title: Basket centrifuge

Abstract: A feed mixture of liquid and solids is delivered into a central nave at the lower portion of a basket mounted for rotation about a vertical axis. The nave is rigidly connected to the outer portion of the basket by spoke-like tubes in which the feed mixture is accelerated while flowing from the nave into a channel extending around the rotation axis and opening upwardly into the separating chamber in the basket's outer portion. To further reduce turbulence, the channel is closed at the top in the regions where the spoke-like tubes communicate with the channel. A discharge shoe in the basket is movable relative thereto to plow accumulated solids from the outer part of the separating chamber, so that the plowed solids fall through bottom openings of the basket between the spoke-like tubes.
