Abstract
A high capacity continuous solid bowl centrifuge is disclosed having longitudinal vanes which cooperate with helical flights to form longitudinal channels. The longitudinal vanes may be curved vanes or they may be planar vanes disposed either radially or at an acute angle relative to a radius from the longitudinal axis of the centrifuge. In operation, the solids/liquid mixture fed into the centrifuge is separated, and the liquids move in a "plug-flow" manner in the longitudinal channels parallel to the axis of rotation, toward effluent discharge ports disposed at one end of the centrifuge. The separated heavier solids are moved by the flights toward the opposite end of the centrifuge where they exit through a solids discharge port.
