The present invention provides a crushing device for grit manufacture that can be operated by a single driving source and that crushes metal material in a stable manner while maintaining a high durability. The present invention is a crushing device for grit manufacture, in which the metal material is crushed between a pair of metal rolls (16, 18) arranged in parallel so as to be capable of rotation, and grit is manufactured. One of the metal rolls is the driving roll (16), which is driven to rotate by a driving source (66) connected by a drive belt (74), and the other metal roll is the driven roll (18). The driven roll (18) is arranged between the driving roll (16) and the driving source (66) in a plane parallel to the orbital plane of the drive belt (74). |
