PURPOSE: To provide an impact head crusher having mounting surfaces which provide a buffer effect on the failure of impact heads and, consequently, do not render the failure. CONSTITUTION: This impact head crusher is provided with fitting grooves 11 for receiving and bearing the impact heads 5 in their base parts successively with contact surfaces 6. Each impact head 5 is made fittable to the fitting groove 11 by a retaining wedge member 12 disposed between the contact surface 6 and the back of the impact head. This wedge member 12 is adapted to be made movable in nearly a radial direction by means of a threaded bolt 7. |
