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.
Claims16
A metallic based 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. a second end for contact and delivery of momentum to material to be comminuted;
- d. a neck connecting said first hammer end to said second hammer end;
- e. a first shoulder adjacent to and surrounding at least a portion of said rod hole, wherein the thickness of said first shoulder is greater than the thickness of said neck, and wherein the thickness of said first shoulder is greater than the thickness of said first end;
- and
- f. a second shoulder adjacent to and surrounding at least a portion of said rod hole and adjacent said neck, wherein the thickness of said second shoulder is greater than the thickness of said neck, wherein the thickness of said second shoulder is greater than the thickness of said first end, wherein the distance around the periphery of said first shoulder is greater than that of said second shoulder so that said first shoulder and said second shoulder are non-symmetrical about the longitudinal axis of said rod hole.

- d. a neck connecting said first hammer end to said second hammer end;
- e. a first shoulder adjacent to and surrounding a first portion of said rod hole, wherein said first shoulder is positioned between said rod hole and said first end of said hammer;
- and
- f. a second shoulder adjacent to and surrounding a second portion of said rod hole, wherein said second shoulder is adjacent said neck, wherein the distance along the periphery of said second shoulder is less than that of said first shoulder such that said first shoulder and said second shoulder are non-symmetrical about the longitudinal axis of said rod hole.
