SOLUTION: This crushing device 1 is provided with first and a second rotation bodies 3a, 3b; and a motor 9. The first and second rotation bodies 3a, 3b have a plurality of approximately plate-like rotation blades 5a, 5b and the respective rotation blades 5a, 5b are arranged so as to be alternately fitted to each other. A guide means 23 provided with an approximately horizontal guide surface is provided below an area where the rotation blades 5a, 5b are fitted to each other and fixed blades 25a, 25b projected to the first and second rotation bodies 3a, 3b are provided at both sides thereof. A chip passed through the first and second rotation bodies 3a, 3b is abutted on the guide means 23 and attitude is changed. Then, the chip is guided to the fixed blades 25a, 25b along the guide surface and is crushed. COPYRIGHT: (C)2006,JPO&NCIPI
