Abstract
A coarse crusher includes a coarsely crushing unit configured to coarsely crush a sheet piece having an elongated shape, a hopper configured to feed the sheet piece to the coarsely crushing unit through a feed opening, and a posture adjuster configured to adjust posture of the sheet piece. The hopper includes two guide plates facing each other with the feed opening therebetween and configured to guide the sheet piece to the coarsely crushing unit and two coupling plates coupling the two guide plates. The posture adjuster includes a protrusion disposed on at least one of the coupling plates and protruding toward an inner side of the hopper. The posture adjuster is configured to come in contact with the sheet piece being coarsely crushed to adjust the posture of a portion of the sheet piece that is remote from the coarsely crushing unit.
