ABSTRACT:
An improved free swinging hammer mill hammer design is disclosed and described for comminution of materials such as grain and refuse. The hammer design of the present art is adaptable to most hammer mill or grinders having free swinging systems. The improved hammermill hammer may incorporate multiple comminution edges for increased comminution efficiencies. The design as disclosed and claimed may be forged to increase the strength of the hammer. A rod hole shoulder surrounding a portion of the rod hole adjacent the neck may be reduced in the radial dimension. The shape of the hammer body may be varied, as disclosed and claimed, to further improve hammer strength, or reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted.
