ABSTRACT:
The blade of a helical screw conveyor of centrifuge apparatus 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 at or adjacent at least the trunco-conical end of the centrifuge bowl have a generally arcuate configuration concave in the direction of the solids discharge port such that the more distal blade portions peel the separated solids material from the bowl wall 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 attached to a backing plate which in turn is mounted on the leading surface of the blade.
