    摘要: 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.
