  • Patent number: 10792663
    Abstract: A hammer assembly that will mount in a grinder/shredder/hammer mill type machine. A tool holder is milled with dovetail/angular slots along each side of the hammer tool holder, which allows milled blade to slide in to place and be securely held in position. The simple milled slot located in the middle of each blade that allows a single mounting block/bolt to securely hold each blade in position. This results in the ability to rotate and/or interchange blades. The tool holder allows single or multiple blade/hammer inserts to be installed without having to remove a hammer pin, so the tool holder stays in the machine, and the blades can be easily removed. This arrangement allows the tool holder to stay in place, and enables the simple removal of a single bolt and retention block and then flip or rotate the hammer to get additional wear surfaces or install new blades.

  • Patent number: 10758915
    Abstract: A material reduction system and processing tool for a material processing machine. The material reduction system comprises a tool holder fixedly mounted to a rotary drum. A leading member defines a raker surface oriented away from the operating direction at a first predefined angle. A processing tool is removably coupled to the tool holder. A leading face of the processing tool is oriented toward the operating direction at a second predefined angle. The first and second predefined angles are such that material is directed into contact with the reducing member to limit material contact with the tool body and the tool holder. An upper flange of the processing tool directly abuts the tool holder to direct material away from the tool holder. The upper flange and a lower flange define a tool recess configured to receive a projection from the tool holder to prevent rotation of the processing tool.

    Abstract: A splitter is provided for mounting on the leading face of a cutting assembly to be mounted on a brush cutter. In one embodiment, the splitter is preferably mounted below the cutting portion of the tooth such that as wood is cut, the cut wood is directed onto the splitter for further cutting. The tooth is mounted to cut tangentially with respect to the rotation of the cutter, while the splitter cuts radially and outwardly with respect to the rotation of the cutter. In this manner, a cutting mechanism is provided that is capable of cutting tangentially and radially simultaneously. The flow of cut wood is directed out of from the cutting assembly, thus facilitating the removal of the cutting debris away from the tooth holder and the cutting tooth, thereby cleaning the tooth of any debris and preventing wood and other debris from getting lodged within the cutting assembly.

  • Publication number: 20100025511
    Abstract: An improved free swinging hammer mill hammer design is disclosed and described for comminution of materials such as grain and refuse. The hammer design of the present art is adaptable to most hammer mill or grinders having free swinging systems. The improved hammermill hammer may incorporate multiple comminution edges for increased comminuting efficiencies. The design as disclosed and claimed may be forged to increase the strength of the hammer. A rod hole shoulder surrounding a portion of the rod hole adjacent the neck may be reduced in the radial dimension. The shape of the hammer body may be varied, as disclosed and claimed, to further improve hammer strength, or reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted.

  • Patent number: 7494080
    Abstract: An impact hammer mountable to the drum of a rotary crusher employs an attachment bolt having a tapered head which is wedged into a tapered socket in the impact hammer body. A “supernut” is used to secure the bolt to the rotary drum. The supernut is tightened against the rotary shear head until it is snug. Then, threaded locking posts, which pass through the periphery of the supernut, are tightened repeatedly, thereby applying a great deal of tension the bolt shank and effectively stretching it. Any shocks applied to the impact hammer will drive the tapered head of the bolt deeper into the socket of the hammer body block, resulting in the maintenance of a secure hammer-to-drum union. The hammer body also has tungsten carbide chips embedded in a hardfacing material that is applied to the wear surfaces of the hammer.
