  • Patent number: 10710092
    Abstract: Discharge grate components for reducing machines including stops to inhibit pokers within the grate so that the pokers are not ejected from the grate with a high velocity.
    Type: Grant
    Filed: July 13, 2015
    Date of Patent: July 14, 2020
    Assignee: ESCO GROUP LLC

  • Patent number: 10682649
    Abstract: Discharge grates and grate components of reducing equipment have reduced amounts of material to provide lower costs, lower weight, and less scrap while still providing adequate resistance to bending, deflection, and/or warping and suitable material discharge.
    Type: Grant
    Filed: April 8, 2014
    Date of Patent: June 16, 2020

  • Patent number: 10471435
    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.
    Type: Grant

  • Patent number: 10022724
    Abstract: Impact 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. A distal portion includes a primary impact face to initially impact materials to be reduced and a wear edge to subsequently compress, crumble, and/or shear the material against a wall of the equipment. The hammer is provided with a plurality of alternating protrusions and recesses in the distal portion.
    Type: Grant

  • Publication number: 20130233955
    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.
