Methods and apparatus for continuously mixing fluid processing media with pulp suspensions are disclosed. The method includes supplying pulp suspensions to the central portion of the substantially planar radial face of a cylindrical rotor, feeding a fluid processing medium to the pulp suspension as it approaches the rotor face, forming an annular gap at the axial outer surface of the rotor, so that the rapid rotation of the rotor causes the pulp suspension and fluid processing medium to flow radially outward along the planar face and to pass axially through the annular gap, and effecting turbulence between the pulp suspension and the fluid processing medium at the entrance to that gap. The apparatus disclosed includes a cylindrical rotor having a substantially planar radial face and an axial outer surface, a housing surrounding the rotor including a pulp suspension inlet facing the center of the radial face of the rotor, and an outlet proximate to its axial outer surface, an annular gap between the axial outer surface and the housing along a predetermined portion of the axial outer surface of the rotor, a processing medium inlet for feeding the fluid processing medium to the pulp suspension inlet, and turbulence creating fingers located at the periphery of the substantially planar radial face of the rotor to create turbulence in the pulp suspension at the entrance to the annular gap.
