Assignee:

ESCO Corporation - Portland OR

International Classification:

B02C 13/28

US Classification:

2411891, 241197

Abstract:

Shredder hammers having first and second major surfaces on opposing sides, and a circumferential edge. The hammer includes a mounting portion and a working portion. The mounting portion defines a mounting aperture that extends from the first major surface to the second major surface, and is configured to receive a hammer mounting pin. The working portion includes at least one recess in at least one of the first and second major surfaces with opposed walls that extend away from a distal portion of the circumferential edge. The hammers are used in shredding systems for shredding material.

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.
