Estimating the term…
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 method of operating a shredding machine comprising mounting a hammer in a shredding chamber by a support pin through a mounting hole of the hammer, the hammer having a center of gravity, a center of gravity axis extending through a center of the mounting hole and the center of gravity, a leading portion on one side of the center of gravity axis including a leading surface that faces in the direction of hammer rotation in an unloaded steady state condition, and a trailing portion with a trailing surface on the other side of the center of gravity axis that extends laterally farther from the center of gravity axis than the leading portion where at least segments of the leading and trailing surfaces diverge as they extend away from the mounting hole, rotating the rotary shredding head such that the leading surface faces in the direction of rotation and feeding material into the shredding machine so that the leading surface impacts the target material fed into the shredding machine.
