Abstract:
1. A solid bowl screw centrifuge, comprising: a centrifuging chamber having a rotatable screw with a center axis; a rotatable drum surrounding the centrifuging chamber; an axially extending inflow tube for guiding material to be centrifuged into a distributor, the distributor being oriented in a substantially perpendicular manner with respect to the center axis of the screw and configured for introducing the material to be centrifuged into the centrifuging chamber; the distributor further including at least one wall having a surface structure that includes projections configured such that a substantial portion of the material to be centrifuged flowing through the distributor must flow around at least one of the projections on an essentially radial path that extends in a direction of a centrifugal force such that the projections exercise a braking effect which counteracts an acceleration of the material to be centrifuged; and wherein the at least one wall of the distributor has at least two radially and mutually offset rows of projections, the projections being axially offset with respect to one another such that essentially neither radial flow channels nor flow channels which extend essentially in the direction of the centrifugal force are formed on the at least one wall.
