A pulp refining apparatus of the type in which two intermeshing rotary screws (2, 3) are driven synchronously within a housing (1) provided with a material inlet (4) and a material outlet (8), the treated material passing from the inlet to the outlet while being compressively treated at a high dry-matter concentration between the intermeshing screw threads, has at least one of the screws (3) arranged for pivotal swinging movement in relation to the other (2) in a way permitting selective adjustment of the width of the treating gap between the intermeshing screw threads and selective control of the treating conditions to which the material is exposed. |
