ABSTRACT:
A fluid stream solids separator provides a curved flow confining chamber to cause heavier constituents in a fluid stream, or slurry, flowing in the resulting curved path in the chamber to migrate radially outward with time and distance travelled. At least one skimmer blade is provided to protrude some distance into the stream from the radially outer flow boundary. The blade skims a strata of the heavier constituents from the stream and directs skimmed products into a separate exit flow path. A series of skimmer blades can be used to skim consecutive strata from the main stream. Fluid flow confining chambers of both mushroom and cylindrical shape are provided. Adjustment means, optionally provided, move the input guiding surfaces to change velocity and move the skimmer blades to change the thickness of strata extracted from the main stream.
