ABSTRACT:
A solid bowl centrifuge for dewatering sludge exhibiting a conical solid bowl and an inner rotor part which revolving at different speeds and has apparatus for axially transporting solid components for improved separating and reduced energy consumption. The sludge is introduced at a tapered end and solid components are discharge at an expanded end. Introduction of sludge is effected through a radial inlet channel(s). Surface elements are attached to the inner rotor by holder arms and are located at a slight distance from the inner wall of the solid bowl drum. A surface element free axial passage channel is defined between the inner rotor wall and the solid bowl drum extending at least 50% of the radial distance between the rotor wall and the drum. A baffle plate is mounted on the inner rotor at the wide end of the drum leaving an annular gap or passage between a compacting space and a sediment discharge which exhibits a radially inwardly directed sediment outlet channel(s). The separated liquid is drained through a liquid outlet channel(s) from the compacting space. The liquid outlet is mounted on the inner rotor.
