PCT No. PCT/SE79/00104 Sec. 371 Date Dec. 28, 1979 Sec. 102(e) Date Dec. 17, 1979 PCT Filed Apr. 27, 1979 PCT Pub. No. WO79/01002 PCT Pub. Date Nov. 29, 1979. A pulp refining apparatus of the type in which two intermeshing rotary screws are driven synchronously within a housing provided with a material inlet and a material outlet, 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 arranged for pivotal swinging movement in relation to the other 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.
