  • Patent number: 7946513
    Abstract: The present invention regulates the delivery of feedstock to the fragmentation zone in a gravity-fed comminuting machine and reduces the ejection of feed materials by means of a rotating cylinder located at an offset position above the rotor. Rotationally mounted on an axis parallel to and above, but offset from, the axis of the rotor, this cylinder serves primarily as a striking surface, or anvil. The continual rotation of the anvil, in the opposite rotational direction as the rotor and with much slower rotational speed, assists in agitating the feed material, alleviating the problems of feed chute obstructions and feed aggregation. The cylinder forces the feed materials into contact with the rotor teeth through continuous rotation and provides a novel tooth design to improve efficacy and reduce wear.

  • Patent number: 4592516
    Abstract: A device for breaking coal and for separating predetermined size coal particles and impurities therefrom. A supply of coal containing rock, shale and other impurities is dumped in a hopper through a top opening. A zigzag-shaped passageway extends from the top to the bottom of the hopper and has a single double action accelerator rotor or a pair of accelerator rotors mounted therein. The rotors increase the speed of the deposited materials that are moving by gravity through the passageway by striking the material and propelling it in the same direction that it was moving prior to being struck. The coal is split upon impact against splitting grates. Chutes located beneath the splitting grates receive the coal particles which pass through sized openings formed in the grates and deposit it in a collection area. The rotors each include a shaft with a plurality of radially outwardly extending blades.

  • Patent number: 4418872
    Abstract: A feeder/crusher machine for use in underground coal or ore mines for receiving and crushing mined material and feeding the crushed product to a stationary conveyor in the mine material transport system. It comprises a tramming unit supporting a feeding and crushing unit having an elongated body with a crushing section located intermediate receiving and discharge sections at opposite ends of the body. A conveyor has an upper, carrying run movable through the crushing section in a horizontal plane. A pair of breaker drums are mounted immediately above the conveyor in the crushing section and are rotatable about transversely spaced, parallel vertical axes. Because the breaker drums are rotatable about vertical axes, teeth on their peripheries move horizontally, parallel to the plane of the conveyor carrying run. Further, the teeth move in the same direction as the conveyor at the location between the drums where crushing occurs.

  • Patent number: 4201346
    Abstract: A device for crushing sinter and other material of like consistency is disclosed wherein the flow sinter material is deployed against an impact table which directs the sinter material downward onto a series of vertically disposed discs fixed to a common means of rotation. The common means of rotation intersects each disc through its central axis. Adjacent to the discs and parallel to the common means of rotation is positioned a shaft upon which are mounted crusher means arranged to intersect and pass between the discs. As sinter is directed downward onto the discs, the crusher means rotates and forces the sinter between the discs, thus crushing it. Heat buildup in the discs is controlled by a means of cooling which impinges on the discs.
