ABSTRACT:
An apparatus for sorting wood chips includes a feeder for supplying wood chips onto a sloping support surface to slide along the support surface over a slit extending thereacross. The slit is configured to provide an impulse action by means of a continuous gas flow on the chips or the fines particles presently in line with the slit. The bottom end of the support surface upstream of the slit is provided with a section (a) diverging from the rest of the support surface in terms of its gradient, over which section an angle of inclination (β) relative to the horizontal plane is smaller than an angle of inclination (α) of the support surface upstream of the same in the advancing direction of the wood chips.
