Abstract

The invention relates to an apparatus for treating a fluid containing at least two fractions, which apparatus includes a rotationally symmetrical casing (4) which is firmly connected to a driven, mounted axle (1), with the axle (1), and thereby the casing (4), being caused to rotate around an axis of rotation (C), in addition to which the casing (4) is provided with inlet members (9) for the fluid which is to be treated and with outlet members (14, 16). A number of guiding blades (30) inside the casing (4) are firmly connected to the said axle (1) so that they rotate with it, with the said guiding blades (30) extending from the said axis of rotation (C) out towards the inner walls of the said casing (4).
