Improved free-swinging hammermill hammer configurations are disclosed and described for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The configurations as disclosed incorporate comminution edges having increased hardness for longer operational run times. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. More particularly, a method for replacing hammers and spacers includes pre-assembling hammers, spacers, hammer saddles, locking collars, or any combination thereof and temporarily attaching them to one another before placement onto a hammermill rod. Once placed on the hammermill rod, the temporary attachment is broken such that the hammers within the pre-assembled group may move freely with respect to one another.

The various embodiments disclosed and pictured illustrate a hammer cluster for comminuting various materials. The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. An illustrative embodiment of a hammer cluster may include at least two hammers each having a connection portion, a contact portion, and a neck connecting the contact and connection portions. The connection portions may include a connection aperture with a relief cavity having a tab on either side thereof. A collar having a collar gap defined by two collar edges may be inserted through connection apertures of each hammer. The collar edges may engage the respective tabs such that the hammers and the collar may rotate about a rod positioned within the collar as a singular unit.

Improved free-swinging hammermill hammer configurations are disclosed and described for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The configurations as disclosed and claimed are non-forged and incorporate a saddle or hammer mouth. The merging of a hammer and saddle improves 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 configurations incorporate comminution edges having increased hardness for longer operational run times. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. The improved configurations may incorporate hammermill rod hole of varying shapes and sizes and saddles of varying shapes and sizes or the use of non-planar hammer bodies that have a recessed or protruding surface.

Shredder hammers having first and second major surfaces on opposing sides, and a circumferential edge. A mounting portion includes a mounting hole that extends from the first major surface to the second major surface, and is configured to receive a hammer mounting pin for mounting in a reducing system. The circumferential edge includes a primary impact face to initially impact materials to be reduced and a wear edge to subsequently crush and shear the material against a wall of the equipment. The hammer is biased forward on the pin to admit more material to be crushed between the wear edge and the grates.

A multi-piece hammer for use in a reducing machine. The multi-piece hammer includes a base to be mounted to the reducing machine, a replaceable tip to be mounted to the base and to impact the material to be reduced, and a retainer to secure the replaceable tip to the base. The replaceable tip has a cavity with a single rail or groove that corresponds to a single groove or rail on the base.
