Abstract

Described is .a sorting device intended in particular for the fibre suspensions produced when paper is pulped. Fitted to the body (1) of a rotor are vanes (2) which extend out from the surface of the rotor body (1) towards a screen wall (4). The supports for the vanes (2) are made up of several parts and may, for instance, consist o:f two parts - a vane carrier (10,10') and a strut (5,5'). The strut (5,5') is attached to the rotor body (1) by welding (6) for instance. The vane carrier (10,10') and the strut (5,5') are detachably connected to each other so that they cannot rotate, for instance by a screw joint (8,17). To secure the two parts (5,10; 5',10') against rotation, the joint is preferably of the inter-locking type.
