Abstract:
A high-speed crushing apparatus, comprising:a hopper into which a scrap wood is charged;two cutting edges for slicing the scrap wood from the hopper into pieces, one of which is an upper rotary-type and the other a lower stationary-type;the two cutting edges being so disposed downstream of the hopper along the path of the scrap wood that the scrap wood within the hopper is delivered to the two cutting edges;a crusher including a shaft facing the rotary-type cutting edge and a plurality of cutters attached perpendicularly and slidably to the shaft under rotation of the shaft, the crusher disposed downstream of the two cutting edges along the path of the pieces, the shaft being adjusted rotatably in the same rotation direction as the rotary-type cutting edge; anda guide plate extending from below the rotary-type cutting edge and downstream of the stationary-type cutting edge to the crusher, the guide plate being disposed away from the rotary-type cutting edge by a space through which, when the rotary-type cutting is being rotated, the pieces can be passed to be thrown backward to the cutters of the crusher being rotated.
