Abstract

Device for treating pref. cellulosic suspension, consisting of housing (10) mounted on support, comprises following sections: (a) injection chamber (32) between two disc-shaped walls (34) rotating around same rotation centre as axle; (b) at least one inlet inside inner part of chamber for suspension; (c) outlet for treated suspension in outer part (6) of chamber; (d) extraction vessel (70) outside walls of injection chamber; (e) openings for filtrate between injection chamber and extraction vessel within at least one circular zone formed by projecting radial part of chamber walls; (f) outlet (70) for filtrate from extraction chamber; and (g) part for changing distance between walls in injection chamber and therefore size of chamber.
