Patent

CA 2190601

A pair of co-operating refining elements (10,11) intended for a disc refiner with two opposed refining discs, one of which is stationary (stator) and the other one is rotary (rotor), for the working of lignocellulosic fiber material in a refining gap (12) between the co-operating refining elements (10, 11). The refining elements are provided with a pattern of bars (13-16) and intermediate grooves. Each bar is formed with a plurality of high bar portions (13,15) and intermediate low bar portions (14,16), counted in radial direction. High bar portions (13,15) are located directly in front of low bar portions (14,16) on opposed co-operating refining elements (10,11). The length of the high bar portions (15) on refining elements (11) of the rotor exceeds the length of the high bar portions (13) on refining elements (10) of the stator.

Paire d'éléments de raffinage (10, 11) d'une raffineuse à deux disques de raffinage opposés dont l'un est fixe (stator) et l'autre mobile (rotor) et servant à traiter des matériaux ligno-cellulosiques dans l'espace de raffinage (12) compris entre ces éléments (10, 11), qui agissent en coopération. Lesdits éléments (12) sont constitués de barres (13-16) et de sillons intermédiaires. Chacune des barres comprend une série de portions hautes (13, 15) et de portions basses intermédiaires (14, 16) se succédant dans le sens radial. Les portions hautes (13, 15) sont situées directement face aux portions basses (14, 16) sur les deux éléments de raffinage opposés (10, 11) qui coopèrent. La longueur des portions hautes (15) de l'élément de raffinage (11) du rotor excède celle des portions hautes (13) de l'élément de raffinage (10) du stator.
