ABSTRACT:
Solid-bowl helical centrifuge for separating a suspension, with a stationarily secured intake pipe (31) for supplying the suspension from a stationary infeed point outside the centrifuge to a separation space (3) left between the screw (2) and the bowl (1), whereby, to prevent obstructions due to centrifugal force and malfunctions due to radial displacements and ensure low-maintenance operation, the intake pipe (31) extends into an intake space (32) inside the screw and the end (34) at that location rests against a component (36 and 35, 36 and 38, 36, or 43), which is secured to the screw, by way of a friction bearing (12) with two halves (14 and 15) that are made of a ceramic material where they contact each other.
