Abstract
An anvil assembly for a vertical shaft impact rock crushing machine includes a plurality of anvils and anvil holders, each anvil holder including an anchor plate and a buttress wall, the anchor plate having dual tapered shoulders and the buttress wall extending perpendicularly from one side of the anchor plate. The rear face of each anvil includes dual vertically-mirroring docking ports each having dual, inwardly-oriented, angularly inclined side channels. In a mounted configuration the shoulders of each anchor plate are detachably captured in the side channels of one of the docking ports, thereby supporting each anvil on the anvil holder and securing it to the crushing machine.
Claims21
An anvil assembly for mounting to a floor of an anvil ring of a vertical shaft impact rock crushing machine, the crushing machine having a rotor rotatably disposed in the anvil ring, the anvil assembly comprising:
- a plurality of anvil holders for fastening to a floor of an anvil ring, each of the plurality of anvil holders including an anchor plate, the anchor plate having dual tapered shoulders,
- a plurality of anvils, each of the plurality of anvils having front, rear, top and bottom faces, the front face forming an impact surface against which matter ejected from a rotor strikes, the rear face including at least one docking port, each of the at least one docking ports having dual, inwardly-oriented, side channels extending from one of the top and bottom faces to a middle portion of the anvil located about halfway between the top and bottom faces, the side channels spaced apart by a tapered width narrower at the middle portion than at the top or bottom face, and
- a mounted configuration in which the shoulders of each of the plurality of anvil holders are detachably captured in the side channels of the at least one docking port of one of the plurality of anvils, thereby supporting the plurality of anvils on the plurality of anvil holders for securing the plurality of anvils in the anvil ring.
An anvil assembly for mounting to a floor of an anvil ring of a vertical shaft impact rock crushing machine, the crushing machine having a rotor rotatably disposed in the anvil ring, the anvil assembly comprising:
- a plurality of anvil holders for fastening to a floor of an anvil ring, each of the plurality of anvil holders including an anchor plate and a buttress wall, the anchor plate having dual tapered shoulders, the buttress wall extending perpendicularly from one side of the anchor plate,
- a plurality of anvils, each of the plurality of anvils having front, rear, top and bottom faces, the front face forming an impact surface against which matter ejected from a rotor strikes, the rear face including top and bottom docking ports, each of the docking ports having dual, inwardly-oriented, side channels, the top docking port having side channels extending from the top face to a middle portion of the anvil located about halfway between the top and bottom faces, the bottom docking port having side channels extending from the bottom face to the middle portion, the side channels spaced apart by a tapered width narrower at the middle portion than at the top or bottom face, the docking ports being vertical mirror images of each other, and
- a first mounting configuration in which the shoulders of the anchor plate of one of the anvil holders are captured in the side channels of one of the docking ports of the anvil, and
- a second mounting configuration in which said shoulders are captured in the side channels of the other of the docking ports of the anvil.
A method for mounting an anvil assembly to a floor of an anvil ring of a vertical shaft impact rock crushing machine, the crushing machine having a rotor rotatably disposed in the anvil ring, the method comprising:
- placing a plurality of anchor plates on the floor of the anvil ring, each of said anchor plates having dual tapered shoulders, and
- mounting a plurality of anvils on the plurality of anchor plates so that the tapered shoulders of each of said plurality of anchor plates are captured in dual, inwardly-oriented side channels in a rear face of at least one docking of one of said plurality of anvils, and in an orientation such that a front face of each of said plurality of anvils is directed toward the rotor thereby presenting an impact surface for rocks ejected therefrom.
