Abstract
Official abstract text for this publication.
A crushing apparatus includes a first rotary shaft member, a second rotary shaft member, a plurality of first rotary cutters, a plurality of second rotary cutters, a plurality of first spacers, and a plurality of second spacers, the first rotary cutters and the first spacers being alternately disposed in a first axis direction, the second rotary cutters and the second spacers being alternately disposed in the first axis direction, the first rotary cutters and the second rotary cutters each forming a tearing blade that protrudes in a direction perpendicular to the first axis direction, a portion of each of the first rotary cutters and a portion of each of the second rotary cutters overlapping when viewed from the first axis direction, and a gap being provided between the first rotary cutter and the second rotary cutter in the first axis direction.
First claim
Opening claim text (preview).
What is claimed is: 1 . A crushing apparatus comprising: a first rotary shaft member that rotates about a first axis; a second rotary shaft member that rotates about a second axis parallel to the first axis in an opposite direction to a direction in which the first rotary shaft member rotates; a plurality of first rotary cutters provided on the first rotary shaft member and rotating together with the first rotary shaft member; a plurality of second rotary cutters provided on the second rotary shaft member and rotating together with the second rotary shaft member; a plurality of first spacers provided on the first rotary shaft member; and a plurality of second spacers provided on the second rotary shaft member, wherein the first rotary cutters and the first spacers are alternately disposed in a first axis direction, the second rotary cutters and the second spacers are alternately disposed in the first axis direction, the first rotary cutters and the second rotary cutters each form a tearing blade that protrudes in a direction perpendicular to the first axis direction, a portion of each of the first rotary cutters and a portion of each of the second rotary cutters overlap when viewed from the first axis direction, and a gap is provided between the first rotary cutter and the second rotary cutter in the first axis direction. 2 . The crushing apparatus according to claim 1 , wherein the first rotary cutter and the second rotary cutter each include a first surface and a second surface that are perpendicular to the first axis direction, a third surface formed in a thickness direction of the first rotary cutter and the second rotary cutter, the tearing blade being provided on the third surface, and a ripping blade protruding in a direction intersecting the second surface between the second surface and the third surface, and a size of the gap is larger than a size of the ripping blade in the first axis direction. 3 . The crushing apparatus according to claim 2 , wherein the third surface includes a protruding portion protruding in the direction perpendicular to the first axis direction, and a corner portion of the protruding portion provided on the third surface has an obtuse angle of 90° or more, or the corner portion is chamfered. 4 . The crushing apparatus according to claim 1 , further comprising: a first gap-forming member provided on the first rotary shaft member and forming the gap; and a second gap-forming member provided on the second rotary shaft member and forming the gap.
