PROBLEM TO BE SOLVED: To provide a hammer head capable of adjusting an abrasion characteristic to impact in crushing or pulverization.;SOLUTION: A hammer head is fixed to an outer peripheral part of a rotatable rotor, and executes the crushing or the pulverization between a repulsive stationary blade arranged around the rotor and itself. The hammer head has a body part 32 extending over the predetermined length toward the repulsive stationary blade from the rotor, and the body part has hardening build-up parts 36A and 36B for constituting an impact load receiving surface on the rotational directional advance side of an opposite side end part of the other end part and soft steel parts 38A and 38B provided inside the hardening build-up parts and softer than the hardening build-up parts, and the hardening build-up parts form the first edges 42A and 42B by the impact load receiving surface and an end surface of crossing with the impact load receiving surface, and the soft steel parts have a soft steel part end surface adjacent to the end surface and flush with the end surface so as to abrade by following abrasion of the first edges of the hardening build-up parts caused by the crushing or the pulverization.;COPYRIGHT: (C)2014,JPO&INPIT
