The vessel has a mixture intake at a forward end and a concentrated mixture outlet and a fluid medium outlet at the rearward end. Mounted on the shaft, downstream of the stabilizer and of the stablizer which imparts a spin to the incoming mixture. Also mounted on the shaft, downstream of the stabilizer and of the mixture intake is an intake impeller means for removing substantially only the fluid medium from the mixture which is located in the annular channel between the vessel and the rotor to an internal passageway located inside the rotor. The improvement comprises an annular seal located between the rotor and the vessel separating the concentrated mixture outlet and the fluid medium outlet. A further improvement in a preferred embodiment comprises a cylindrical impeller means having a plurality of axially extending slots angularly cut in the cylinder wall.
