ABSTRACT:
A centrifugal jig screen with a rotating hutch is supplied with inwardly directed pulses by overlapping fluid supply nozzles and pulse blocks coaxially arranged about the jig axis. Fluid not directed to the hutch interior in sharply defined pulses is diverted into a surrounding shroud, permitting the incoming fluid flow to be substantially uninterrupted during jig operation. Wedge surfaces about the hutch prevent buildup of separated materials as the are discharged from the hutch.
