摘要： A coarse crusher includes a coarsely crushing unit configured to coarsely crush a sheet piece having an elongated shape, a hopper having a feed opening through which the sheet piece is fed to the coarsely crushing unit, the hopper being configured to feed the sheet piece putted into the hopper to the coarsely crushing unit through the 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 to each other. 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 by the coarsely crushing unit to adjust the posture of a portion of the sheet piece that is remote from the coarsely crushing unit.
