ABSTRACT:
The invention concerns a wood pulper of the kind in which wood is fed via a hopper having advancing elements arranged on two opposite sides by which wood is advanced to a grinding stone. The invention is characterized in that said advancing elements comprise a plurality of driven shafts which are arranged parallel to and adjacent each other substantially transverse to the feed direction, said shafts being equipped with a plurality of toothed discs lying adjacent to each other. This arrangement enables the driving force to be distributed over a plurality of feed shafts, so that a continuous compression can be obtained which increases as the wood feeds through the hopper.
