Abstract:
A high speed centrifuge comprising:(a) an elongate conic rotatable housing having an inner surface therein tapering from one end to define a beach at the tapered end;(b) a feed tube introduced into said housing for delivering a feed liquid with heavier particles therein;(c) a flited conveyor in said housing having flites thereon wherein said flites are operatively scrolled to move heavier particles along the housing toward the tapered end;(d) an internal surface within said housing defining a pond therein to receive the feed liquid so that the pond interacts with the flited conveyor to thereby enable separation by operation of said flited conveyor within said housing;(e) a stack of closely spaced discs extending into said pond rotating with said housing and having a spacing there between so that liquid from the pond flows between said discs toward the top of said pond, and additionally to permit heavier particles in the liquid to migrate between said discs; and(f) a disc stack conveyor adjacent to said disc stack for conveying heavier particles to said flited conveyor for scrolling there along and to said tapered end.
