Abstract
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.
