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.
