ABSTRACT:
An apparatus for treating cellulose pulp having a consistency above the flowage limit provided with two shafts (1, 2) rotating in the same axial plane and each carrying working disks (8) the cylinders of rotation of which are in mutually intermeshing engagement in a working zone and which are driven within a housing (3) which conforms to the common cylinder-of-rotation space of the disks carried by the shafts and is provided with a pulp inlet (4) and a pulp outlet (5). The working disks are constituted of a number of radially directed disks in mutually co-operative positions for working of the pulp between opposed disk surfaces (11, 12), the pulp being fed from the inlet to the outlet with the aid of mutually co-operating feeding screw threads (9) carried by the shafts.
