ABSTRACT:
A particle discharge mechanism is described for use on a centrifugal dewatering system, which is of relatively simple and rugged construction. The discharge mechanism includes a pair of concentric ring-like gates (50, 52 in FIG. 2) that can move across a particle discharge passageway (46) extending around a rotating vessel (14). The gates are operated in a sequence to first trap a mass of particles inside the radially outermost gate (52), to close an innermost gate (50) to isolate the trapped particles, and then to open the outermost gate (52) to release the trapped mass. In one procedure, the outermost gate is opened only slightly prior to complete particle release, to remove small amounts of remaining water in the mass of particles.
