The crushing chamber (13) includes an arm (15) radially attached to a rotating shaft (14), and the arm tip (15).
A hammer (21) for crushing the rough stone is attached to a). A most basic example of the hammer (21) of this crusher is shown in FIG. In this hammer (21), a metal base member (22) and a ceramic impact member (23) are bonded with an adhesive to form a crushing block (24), and the crushing block (24) is made of a metal bolt (28). Is fixed to the mounting base (16) of the arm tip (15a). This hammer (21)
, The head (28a) of the metal bolt (28) is exposed on the front surface of the crushing block (24), and the impact member (23) is made of a material having better wear resistance than the bolt (28). Therefore, the bolt head (28a) is worn and disappears before the impact member (23). When the bolt head (28a) disappears, the crushing block even if the impact member (23) is not much worn
(24) falls off from the mounting base (16) and cannot be crushed.

平３−８３６４１号公報）。In order to solve the above-mentioned drawbacks, the inventor of the present invention sits the bolt head inside the impact member, and wears a cap made of wear-resistant material (specifically, ceramic) so as to cover the bolt head. A hammer that has been fitted and bonded has already been proposed (Japanese Utility Model Laid-Open No. 3-83641).

落するという問題が生じる。Ceramics are superior in abrasion resistance to iron or the like, but inferior in impact resistance. Therefore, the impact member or the cap may be partially damaged by the impact when the rough stone is hit. Since the impact member has a predetermined thickness, even if a part of the cap is damaged, it does not hinder the crushing work. However, since the cap has a small diameter and a small thickness, even if a part of the cap is damaged, the fitting adhesive force to the impact member becomes weak. When the mating adhesive strength becomes weak, the cap comes off from the bolt head due to the impact during crushing. When the cap comes off, the crushed grains of the rough stones directly hit the bolt head, and as described above, the bolt head wears first, and eventually it disappears and the crushing block falls off the mounting base at the tip of the arm. .
