Claims

[Claims for Utility Model Registration] 1. A rotating rotor that rotates around a main shaft provided inside a casing, a plurality of strikers fixed to the outer periphery of the rotating rotor, and a plurality of striking elements arranged around the rotating rotor. A repulsion plate is provided at a distance, and the repulsion plate is detachably attached to the tip of the rotating striker in order to crush the raw material splashed by the tip of the rotating striker by colliding with the tip of the striker and the repulsion plate. In a striker for an impact type crusher in which a piece of carbide material is joined to the tip of the striker via a joining base, a mounting member for attaching the joint base to the striking member is provided.
A striker for an impact type crusher, characterized in that it is provided inside a raw material falling curve starting from the outer peripheral end of a joining surface of a piece of carbide material to a joining table. 2. The striker for an impact type crusher as set forth in claim 1 of the utility model registration claim, wherein the outer peripheral end of the joint surface is located in consideration of the amount of wear.
