Abstract

The invention relates to an apparatus for fractionating fiber suspensions, said apparatus including a chamber (22) converging towards its periphery and formed by two annular fiber fractionating means (1, 2), preferably implemented as truncated cones, a collection trough (4) arranged concentric to and at the periphery of the chamber (22) for fibers retained by the fiber fractionating means (1, 2), and agitating means (20) departing from a centrally arranged shaft (19) and rotat­ able therewith, the means (20) having vanes (35) contiguous to the fiber fractionating means (1, 2), the vanes (35) having an engagement area coacting with the fiber fractionating means.
