[ EN ]
nil CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS:

1. An apparatus for processing iron ore, including a mineral breaker as a secondary crusher for crushing the iron ore, wherein the mineral breaker includes a breaker drum mounted in a housing for breaking minerals into smaller pieces.

2. An apparatus for processing iron ore as claimed in claim 1, wherein the mineral breaker has a pair of side by side breaker drums rotatably mounted in a housing.

3. An apparatus for processing iron ore as claimed in claim 2, wherein the pair of breaker drums rotate in opposite directions to facilitate crushing of the minerals between the breaker drums.

4. An apparatus for processing iron ore as claimed in claim 3, wherein each breaker drum is provided with circumferentially extending groups of breaker teeth, the groups being spaced axially along the breaker drum, the axial spacing of groups on one drum being staggered to that on the other drum so that the teeth in a group on one drum pass between an adjacent pair of groups on the other drum.

5. An apparatus for processing iron ore as claimed in claim 1, including a gyratory crusher as a primary stage crusher.

6. An apparatus for processing iron ore as claimed in claim 1 or claim 2, including a cone crusher as a tertiary stage crusher.

7. An apparatus for processing iron ore as claimed in claim 1, wherein the sizer is fed directly from a screen with primary stage crushed mineral.

8. An apparatus for processing iron ore, including a primary crusher, a secondary crusher and a tertiary crusher, wherein the apparatus includes a pair of independently operable conveyors from the primary crusher to the secondary crusher, from the secondary crusher to the tertiary crusher, and/or from the tertiary crusher to a screen which feeds back to the tertiary crusher.

9. An apparatus for processing iron ore as claimed in claim 5, wherein the apparatus has a single primary stage crusher, multiple secondary stage crushers and multiple tertiary stage crushers.

10. An apparatus for processing iron ore as claimed in claim 6, wherein the apparatus has a single primary stage crusher, two secondary stage crushers and three tertiary stage crushers.

11. An apparatus for processing iron ore, including at least one conveyor, wherein each conveyors of the apparatus has a fixed single discharge point.

12. An apparatus for processing iron ore, including a primary crusher and a secondary crusher, wherein the secondary crusher is arranged to be fed from the primary crusher.

13. An apparatus as claimed in claim 12, wherein the secondary crusher is arranged to be fed directly from the primary crusher.

14. An apparatus as claimed in claim 13, wherein the secondary crusher is fed directly from the primary crusher in that there is no bin to accumulate material to be fed to the secondary crusher.

15. An apparatus as claimed in claim 12, wherein the secondary crusher is arranged to be fed directly from a screen used to filter material from the primary crusher according to material size.

16. An apparatus for processing iron ore, including a single yard belt located beneath a reversible stacker/reclaimer such that the single yard belt is configured to provide throughload functionality for directly loading the iron ore on a train, stacking functionality for stacking the iron ore on a stockpile, and reclaiming functionality for reclaiming iron ore from the stockpile to the train.

17. An apparatus for processing iron ore, including a single belt arranged to transport iron ore material from a tertiary crusher, wherein the single belt is located beneath a reversible stacker/recl aimer such that the single belt is configured to provide throughload functionality for directly loading the iron ore material on a transport, stacking functionality for stacking the iron ore material on a stockpile, and reclaiming functionality for reclaiming iron ore material from the stockpile to the train.

18. An apparatus for processing iron ore, including a mineral breaker as a secondary stage crusher for crushing the iron ore, wherein the mineral breaker includes a breaker drum mounted in a housing for breaking primary stage coarse minerals into smaller pieces suitable for tertiary stage crushing.

19. An apparatus for processing iron ore, including a primary stage crusher, a secondary stage crusher and a tertiary stage crusher, wherein the apparatus includes multiple independently operable secondary screening, crushing and conveying circuits from the primary stage crusher to the tertiary stage crusher, and multiple independently operable tertiary screening, crushing and conveying circuits from the secondary to the product stage, whereby the apparatus also allows for each circuit to cross feed between parallel circuits.

20. An apparatus for processing iron ore, including at least one conveyor, wherein all conveyors of the apparatus have a fixed single discharge point.

21. An apparatus for processing iron ore, including a primary crusher and a secondary crusher, wherein the secondary crusher is arranged to be fed from the primary crusher without material storage between the crushers.
