摘要

A refining segment (7; 17; 27; 37) intended to constitute at least part of the surface refining a rotatable refining disc included in refining apparatus for disintegrating and refining material containing lignocellulose in a hollow refining between two opposing refining discs (4,5) rotary relative to each other, and which segment is a wear member that is replaced at regular intervals characterized in that it is provided with at least one cleaning member (10; 20; 30; 40) arranged protruding from the periphery of the refining segment in a space between the outer edge of the refining segment and the inside of the refiner housing (3) in which the refining discs (4 placed. 5) to clear away material that has collected outside the outer edge of the refining disc.
