Hammer head and a method of manufacturing the same, as well as crushing machine having the hammer head

摘要

[Challenge] I provide an adjustable hammer head wear characteristics against the impact of the time of crushing or grinding. A is fixed to the outer peripheral part of the rotatable rotor, the hammer head for crushing or grinding between repulsion fixed blade which is disposed around the rotor, the hammer head, the reflected repellent fixed blade from the rotor a main body 32 extending over a predetermined length toward the, body part, the rotation direction leading side of the opposite end of the other end, hardfacing portion constituting the impact load receiving surface 36A, and 36B, soft mild steel portion 38A than curing buildup portion provided on the inside of the cured meat overlaid portion, and a 38B, is cured built-up portion, and the impact load receiving surface, the shock first edge 42A, and 42B is formed by the end face intersecting with the load receiving surface, soft steel part, as worn by following wear of the first edge of the hardfacing portion due to the crushing or grinding, Adjacent to the end face and having the end face and the surface of mild steel end face of the one.
