Hydrocyclone with fines depletion in the cyclone underflow

摘要

The invention relates to a hydrocyclone (1) with an inlet region (2) with a tangential inlet (4) for a feedbeingbeet (6) and a further separation region (3) adjoining the feed region (2) with an underflow discharge pipe (8) (9), which projects axially into the interior of the hydrocyclone (1) in the form of an immersion tube. In the region of the tangential inlet (4), a further inlet (5) is provided for supplying a barrier fluid flow (7), the barrier fluid (7) and the feedbeet (6) Are separated from each other. According to the invention, the separation area (3) consists of a conical section (15) and a cylindrical section (18) adjoining it above the underflow discharge pipe (8).
