ABSTRACT:
Screw conveyor of solid bowl centrifuge has its flight member modified at the bowl dry beach area by welding sheet metal, for example, to trailing surfaces of the flight forming a chamber for rinse liquid driven thereinto. Leading or working surfaces of the flight are provided with a plurality of series of orifices per 360.degree. revolution thereof, each series comprising spaced orifices extending inwardly from a distal portion thereof and preferentially angled therethrough. Overflow passageways with cooperating baffles are provided. Thus, rinse liquid passes onto solids pile surfaces through orifices immediately inwardly thereof as well as through orifices submerged by the solids for passage of rinse liquid thereinto.
