  • Patent number: 9731434
    Abstract: Plastic sheet elements (19) having a size and deformation suitable for use as a filling material in pillows, duvets and the like are manufactured by feeding one or more plastic sheets to a shredding apparatus (6) which has a rotating drum (9). Loosely hanging knives (12) are mounted (11) near an outermost edge of the drum (9), and are pivoted outwards during rotation to thereby cut, deform and twist the sheet to form “curly” elements (19), which are sucked out through openings (14) in a screen (8) located below the drum (9). By adjusting the feeding of the sheet (4), the rotation of the drum (9) and the magnitude of the negative pressure, various sizes and configurations of cut individual sheet elements (19) are produced.

    Abstract: A litter management device, such as a device configured to disintegrate and/or de-cake caked litter from poultry is described. In some embodiments, the litter management device includes a litter de-caking mechanism contained within a housing, which is supported by a movable frame. The litter de-caking mechanism includes one or more hammers flexibly attached, such as via chains, to a rotation bar, enabling the hammers to rotate in a circular motion around the rotation bar and within the housing. The rotation of the hammers causes the hammers to strike, often at high speeds, caked litter within a target area, which disintegrates the caked litter, allowing for the removal of the caked litter from an area generally used by poultry, among other benefits.

    Abstract: A rotor assembly for a tree cutting attachment for a skid loader. The rotor assembly is made up of a central driven shaft journaled for rotation in the frame of the tree cutting attachment. Circular endplates are disposed proximately on the opposed ends of the central driven shaft. Two diametrically opposed rows of regularly spaced-apart semicircular support plates extend between the circular end plates. The semicircular support plates are held in parallel-spaced relationship by a plurality of equally circumferentially spaced bars extending between the endplates. Swinging hammers are mounted for free pivotal movement in an alternating pattern between the support plates. Each hammer includes a main shaft extending between the support plates, a body member pivotally connected to the main shaft at the pivot axis parallel to and spaced from the central driven shaft and a generally flat tooth member extending radially outward from the body member.

  • Patent number: 7819352
    Abstract: A hammer for use in a rotatable hammermill assembly comprising a first end for securement within a hammermill assembly, wherein a rod hole is formed in the second end, wherein the rod hole is centered in the first end for engagement with and attachment to the hammermill assembly is disclosed. The hammer also has a second end for contact and delivery of momentum to material to be comminuted, wherein the second end includes at least two blades. A neck connects the first end to the second end. In some embodiments the thickness of the neck may be less than the thickness of the first end or of any of the blades. In some embodiments the rod hole is surrounded by one or more rod hole shoulders. In other embodiments a notch is positioned in the rod hole along the longitudinal axis thereof.

  • Publication number: 20100213301
    Abstract: Shredder hammers include a hammer pin opening in which at least some portion of the interior surface is curved in a direction moving from one major surface of the shredder hammer to the other. This interior surface may be smoothly formed as an arc of a circle, as a parabola, as a hyperbola, or as another curved surface, with the local extrema within the interior of the hole (e.g., at or near the center). Providing the curved interior surface helps vary and disperse the locations where force is absorbed due to contact between the hammer pin and the walls defining the hammer pin opening when the shredding hammer blade contacts the material to be shredded. Other structures include engagement between the hammer pin and the hammer as part of a bushing member, a spool or sleeve member, or a ball swivel member.

  • Publication number: 20100190893
    Abstract: There is described a machine for homogenizing a bitumen-based mixture with polymer granules. The machine includes an outer container and a cylindrical sleeve, which is housed within the outer container and is provided with a perforated side wall, on which a plurality of through apertures is obtained, each of the holes comprising a sharp cutting edge. The machine further includes a homogenizer assembly, which is mounted so as to axially rotate within the sleeve in order to rotate about a vertical axis, and is configured so as to displace, during its rotation, at least part of the bitumen-based mixture and the polymer granules along a direction which is substantially tangential to the inner surface of the perforated side wall of the sleeve so as to induce the polymer granules to impact against the sharp cutting edge of the through apertures.

  • Patent number: 7753302
    Abstract: A rotor of an impact crusher has at least one stellate plate, which can be attached to the rotor shaft. A plurality of paddle-blade type hammer tools are mounted on each stellate plate. The hammer tools are secured above and below the stellate plate by tool mounting brackets having hook-shaped ends that engage with the hammer tools. A respective adapter piece is placed in the stellate plate between the two tool mounting brackets. A retaining bolt penetrates the two tool mounting brackets and the adapter piece. A security slide secures the retaining bolt in position. The hammer tools of the inventive rotor for an impact crusher have a high usage volume and the rotor is extremely user-friendly with respect to the recurring tasks of setting and replacing the hammer tools, without having to loosen screw connections.

  • Publication number: 20100090044
    Abstract: A device for processing feedstock, includes a housing surrounding a processing chamber in which a rotational rotor having processing tools and mounted on a drive shaft is disposed around an axis. The feedstock is fed to the processing chamber via a material inlet and removed from the device via a material outlet. To facilitate assembly and disassembly of the device and to retool, maintain and repair or clean the device, it is provided according to the invention that the housing includes a first end wall, a material element in the shape of a hollow cylinder or hollow truncated cone, and a second end wall which are detachably connected to each other to form the processing chamber. The connection can be made by axially acting clamps, which clamp the first end wall against the second end wall by clamping the casing element.

  • 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.
