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 design as disclosed and claimed is forged increasing the strength of the hammer. The shape of hammer as disclosed and claimed uses this improved strength to reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted. The improved design incorporates comminution edges having increased hardness for longer operational run times.

An improved metallic based forged hammer for use in a rotatable hammermill assembly comprising:
- a. a first end for securement within said hammermill assembly;
- b. a rod hole, said rod hole centered in said first end for engagement with and attachment to said hammermill assembly;
- c. at least one rod hole shoulder surrounds the perimeter of said rod hole;
- d. a second end for contact and delivery of momentum to material to be comminuted wherein said second end has a weld hardened edge;
- and,
- e. a neck connecting said first hammer end to said second hammer end, wherein said thickness of said neck is less than the combined thickness of said rod hole shoulder and said first end of said hammer.
