The device is designed for selective crushing of bulk materials and separation from them of foreign bodies which cannot be crushed. It consists of a roller screen (1) above which operating tools (2) are fitted which on one of their ends rest in a pivot (3) and are freely suspended or supported at their other ends where milling disks (4) are fitted driven by a motor reduction gear (5) by means of transmission mechanisms (6). On every housing of the operating tools (2), outside the hinge (3), a motor reducing gear (5) is mounted with a transmission mechanism - chain (6). The motor reducer gears (5) at every two adjacent operating tools (2) are fitted in a checkered manner toward each other. 2 claims, 2 figures
