Abstract
An apparatus for mixing pulp and fluid includes a housing with a center line an inlet and outlet for the pulp; an inlet for the supply of fluid and two walls are arranged in the housing and have opposite sides which between them define a gap-shaped surface through which the pulp will flow and has inlet and outlet openings communicating with the pulp inlet and outlet respectively; the walls are arranged concentrically in the housing and are non-rotatable with opposite sides thereof being arranged to extend around the central line of the housing, spaced therefrom, the gap-shaped space thus acquiring the shape of a concentric annular gap; the annular gap has an extension in excess of 20 mm in the main flow direction of the medium flowing through it; there is a distribution chamber communicating with and arranged axially upstream of the annular gap in order to distribute the pulp uniformly around the entire concentric inlet opening of the annular gap.
