METHOD OF AND APPARATUS FOR TREATING WOOD CHIPS

摘要

The invention relates to a method of treating wood chips where the chips (C; C'; C") are at first divided into at least three different fractions on the basis of a fragment size, whereupon at least two of the fractions are directed to be treated in specific chip compressors (6) for each fraction, each chip compressor comprising two adjacent profiled rolls (6a, 6b) arranged to rotate around parallel rotation axes. The invention further relates to an apparatus meant for implementing the method.
