    • In a decanter centrifuge, which comprises an outer drum (1) and an inner drum (5) concentric therewith, the two drums being rotatable at different speeds around a common centre axis, said inner drum (5) carries several blades (6, 7) arranged to convey axially in the outer drum (1) sludge having settled on the inside of this drum. The blades (6, 7) are placed in parallel blade rows, each of which extends in a certain pitch along a first helical line (9, 10) around at least part of said centre axis. Each one of the blades extends along a second helical line (29c), which has a pitch opposite the pitch of the first helical line (9, 10). The distance between the rows of blades is substantially larger than the distance between two adjacent blades in one and the same row. Possibly, the inner drum may be provided with only a single row of blades.

    • The blade of a helical screw conveyor (18) of centrifuge apparatus (10) is improved to reduce the amount of torque required in operating the apparatus as well as to produce discharged solids drier than the solids discharged using a conventional blade; the improvement provides that the distal end of the leading surface of the blade (26) at or adjacent at least the trunco-conical end (14) of the centrifuge bowl (12) have a generally arcuate configuration concave (T) in the direction of the solids discharge port (16) such that the more distal blade portions peel the separated solids material (32) from the bowl wall (17) with minimum torque requirements, while the less distal arcuate portions tumble the solids to reduce the moisture content. Typically, the blade's arcuate leading surface is formed by add-on, wear-resistant members (54) attached to a backing plate (50) which in turn is mounted on the leading surface of the blade (26).
