摘要： The invention relates to a method for compression refining of fibers for papermaking, wherein a slurry of fibers with a consistency of between about 2 wt% and 20 wt% of dry fibers in water is subjected to compression forces in an apparatus comprising at least two rolling surfaces with substantially the same velocity. At least one of the surfaces is curved, such that the surfaces move towards each other to achieve a compression force. The position of smallest distance between the surfaces is a closest position. At least one surface is provided with bars and grooves, the bars being at most 16 mm wide and the grooves being sufficiently large to aid in having water pressed out of the paper slurry. The relative speed of the surfaces to each other is such that water leaves the paper slurry upon reaching the closest position, and wherein the bars compress the fibers.
