Abstract
A hydrocyclone for separating lightweight contaminants from a suspension of papermakers'stock as a through-flow design in which an inlet section has a frusto-conical flow controlling wall and has a central flow stabilizer and a tangential inlet. The flow stabilizer has a paraboloid shape and defines with the flow control wall an annular flow space of constant area along the axial length of the flow stabilizer so that fluid entering a tangential inlet at the base of the paraboloid is caused to rotate about the flow stabilizer and is delivered to the interior of the hydrocyclone without a substantial change in axial velocity.
