Fines are separated from wood chips by feeding the chips onto the infeed end of a bed formed by a plurality of knurled rollers separated by narrow gaps and rotated in the same direction. The chips are tumbled by the knurls, and the fines settle into the spaces between the knurls and in the gaps to pass downwardly out of the bed for collection. As the chips tumble, they gradually move to a discharge end of the bed and discharge for further processing.
