To maintain required production levels, Roy Hill required a new crushing facility 6km from the existing infrastructure. Schedule was critical to the success of the project to provide access to new ore bodies prior to depletion of existing. To cater for a diverse range of ore types, Roy Hill’s existing crushing facilities included two trains: jaw crusher for harder material and primary & secondary sizes for softer materials. BG&E Resources identified that the existing arrangement could be optimised catering for all ore types within a single gyratory crusher feed by vibrating grizzly. This arrangement allowed finer material to bypass the crusher reducing the crusher duty by 50% while maintaining required throughout. Additionally, BG&E Resources developed an innovative steel ROM wall concept that integrated the ROM wall with the bin and internal platforming removing the walls. The simplified layout allowed for all assets to be support from the ROM wall removing the need for stringent compaction criteria immediately adjacent to the walls reducing cost and construction time for the ROM walls. BG&E Resources completed all engineering for this crushing facility including civil, structural, mechanical, piping, electrical, instrumentation, controls and shop detailing.
