Abstract

A crusher wear resistant liner for positioning at a crusher bottom shell includes a plurality of modular wear resistant plates mountable at an inside surface of the bottom shell and positioned side-by-side to surround and protect the bottom shell interior. To prevent independent dislodgement of each plate and liner, respective inter-engaging formations are provided at each plate to contact at least one adjacent plate of the assembly to arrest any unintentional downward movement in the event that the primary fixings become ineffective.

First claim

The invention claimed is:

1. A crusher wear resistant liner comprising:
a plurality of wear resistant plates arranged to be mountable adjacent to each other to form the liner, the plurality of wear resistant plates being a plurality of first plates having a first size and a plurality of second plates having a second, different size, each first plate of the plurality of first plates being positionable adjacent each second plate of the plurality of second plates in alternating sequence, each first and second plate of the plurality of wear resistant plates including side edges and a top and a bottom edge to define a perimeter of a respective plate; and
at least one inter-engaging formation attached to each of the plurality of wear resistant plates and configured to engage with an adjacent plate and/or an inter-engaging formation of an adjacent plate to at least partially interlock the adjacent plates and inhibit or prevent independent dislodgement of any of the plurality of wear resistant plates, wherein each inter-engaging formation has a panel shaped body mounted to a rear face of each of the plurality of wear resistant plates.

2. The liner as claimed in claim 1 , wherein the at least one inter-engaging formation includes a first attachment having a flange that projects laterally from at least one side edge of each respective first plate.

3. The liner as claimed in claim 2 , wherein the at least one inter-engaging formation includes a second attachment having a recessed portion to at least partially receive the flange of the first attachment of an adjacent first plate, the recessed portion positioned being adjacent the at least one side edge.

4. The liner as claimed in claim 3 , wherein the second attachment of the at least one inter-engaging formation further includes a flange that projects laterally from the at least one side edge of the each respective second plate.

5. The liner as claimed in claim 2 , wherein the flange of the first attachment extends from a rear face of the first plate a distance beyond the side edge to overlay onto a rear face of an adjacent second plate so as to provide a laterally extending bridge connecting adjacent plates.

6. The liner as claimed in claim 1 , wherein each first plate has a first shape configuration and each second plate has a second shape configuration.

7. The liner as claimed in claim 6 , wherein the first plate has a length in a direction between the top and the bottom edge that is greater than a corresponding length of the second plate and the second plate has a width in a direction between the side edges that is greater than a corresponding width of the first plate.

8. The liner as claimed in claim 1 , wherein each of the plurality of wear resistant plates includes bore holes arranged to receive fasteners.

9. The liner as claimed in claim 8 , wherein each inter-engaging formation includes bore holes positionally spaced apart to align with the bore holes of the plates to receive the fasteners.

10. The liner as claimed in claim 8 , wherein each of the plurality of wear resistant plates includes four bore holes and each inter-engaging formation includes two bore holes, each of the plurality of wear resistant plates having two inter-engaging formations positioned adjacent respective side edges.

11. The liner as claimed in claim 1 , wherein each of the plurality of plates includes a lifting eyelet.

12. The liner as claimed in claim 11 , wherein the lifting eyelet is attached to a respective plate at a rear face of the plate such that a portion of the eyelet is positionable intermediate the.

13. A crusher wear resistant liner comprising:
a plurality of wear resistant plates arranged to be mountable adjacent to each other to form the liner, the plurality of wear resistant plates being a plurality of first plates having a first size and a plurality of second plates having a second, different size, each first plate of the plurality of first plates being positionable adjacent each second plate of the plurality of second plates in alternating sequence, each first and second plate of the plurality of wear resistant plates including side edges and a top and a bottom edge to define a perimeter of a respective plate; and
at least one inter-engaging formation attached to each of the plurality of wear resistant plates and configured to engage with an adjacent plate and/or an inter-engaging formation of an adjacent plate to at least partially interlock and inhibit or prevent independent dislodgement of the plurality of wear resistant plates, wherein the at least one inter-engaging formation includes a first attachment having a flange that projects laterally from at least one side edge of each first plate and a second attachment having a recessed portion to at least partially receive the flange of the first attachment of an adjacent first plate, the recessed portion positioned being adjacent the at least one side edge, wherein the first plate includes the first attachment of the inter-engaging formation at each side edge and the second plate includes the second attachment of the inter-engaging formation at each side edge.

14. A gyratory crusher comprising:
a shell; and
a wear resistant liner positioned at the shell, the liner including a plurality of wear resistant plates mountable at an inside of the shell adjacent to each other to form a liner and to at least partially protect the inside of the shell, the plurality of wear resistant plates including a plurality of first plates having a first size and a plurality of second plates having a second, different size, each first plate of the plurality of first plates being positionable adjacent each second plate of the plurality of second plates in alternating sequence around the inside of the shell, each first and second plate of the plurality of wear resistant plates including side edges and a top and a bottom edge to define a perimeter of a respective plate, and at least one inter-engaging formation configured to engage with an adjacent plate and/or an inter-engaging formation of an adjacent plate to at least partially interlock and inhibit or prevent dislodgement of the liner or the plurality of wear resistant plates from the shell, wherein each inter-engaging formation has a panel shaped body mounted to a rear face of each of the plurality of wear resistant plates.
