A centrifuge rotor comprises a hollow rotary casing provided with windows for discharge of clarified liquid at one end and sediment discharge windows at an opposite end. The casing houses a coaxial hollow screw conveyer, the processed suspension being fed into a cavity of the conveyer from one of its ends. A pack of separating plates is placed in the screw conveyer cavity between the windows for discharge of clarified liquid made in the casing and at least one hollow internal screw conveyer positioned between a pack and the discharge end of the first conveyer, a discharge end of said internal screw conveyer being oriented in the same direction as the external screw conveyer and windows being made in the external screw conveyer wall to let out the sediment discharged from the internal screw conveyer which is rigidly secured to the rotor casing for rotation therewith. A rotor of this design is capable of separate division, thickening, consolidation and transportation of different fractions of the processed suspension permitting division of polydispersed suspensions with a high content of fine fractions with greater efficiency as compared to known centrifuges of the same type.
