Abstract

A refiner plate for the face of a refiner disc comprising a plurality of refiner segments (10) arranged side-by-side on the face of the disc to form a substantially annular refining region. Each refiner segment has a plurality bars (32, 34), chicanes (46) and grooves (36, 38) for refining a lignocellulosic material and forming a zig-zag path for receiving and transmitting steam generated during the refining process. The chicanes define a series of substantially arcuate lines (56) extending from a position intermediate the junction of the inlet and refining zones to the outer edge of the refiner plate in the counter-rotation direction.
