Abstract: Fines, pins, and over-thick wood chips are separated from wood chip material by using a series of three roller screens having chip agitating and conveying protuberances. The screens are arranged and adapted such that over-thick chips are separated by the first screen, fines are separated by the second screen, and pins are separated by the third screen.

Abstract: Wood chips having an acceptable thickness pass between the rollers of a roller screen for collection and over-thick chips discharge from one end of the roller screen for recycling. The rollers have chip agitating protuberances, preferably of pyramidal shape or in the form of spiral ridges. A second roller screen with pyramidal protuberances on its rollers and with its rollers closer together is used to screen out fines, preferably after the fines and acceptable chips pass through the first roller screen. Some of the fines pass through the second roller screen by occupying the valleys between the pyramidal protuberances.

Abstract: 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.
