PROBLEM TO BE SOLVED: To provide a shear type crushing machine allowing even a worker without advanced skill to clean the bearing chamber easily in a short time and a crusher for the machine. SOLUTION: The crusher 12 for shearing and crushing an object material has a housing 13, a rotation shaft 15 rotatably supported to the housing 13 through bearings 20a to 20c, a plurality of cutters 16 having a central hole 39 allowing the rotation shaft 15 to penetrate, a plurality of spacers 17 having a central hole 39 and incorporated on the rotation shaft 15 in one axial direction alternating with the cutters 16, and partition walls 36 and 37 arranged in the housing 13 so as to separate, from the bearing chamber 35, the crushing chamber 34 which includes the cutters 16 and the spacers 17 and is opened in the upper and lower parts. The partition walls 36 and 37 have, in the their upper parts, divided partition walls 36b and 37b divided from the bodies 36a and 37a of the partition walls 36 and 37, respectively. When the divided partition walls 36b and 37b are removed, the bearing chambers 35a and 35b are allowed to communicate with the crushing chamber 34. COPYRIGHT: (C)2008,JPO&INPIT
