BlueScope Steel (Port Kembla, New South Wales, Australia)
BlueScope Steel required detailed design of the new No. 3 Unloaded (3UL) Discharge System to be installed as part of the Commodity Logistics & Import Project (CLIP) for Port Kembla Steelworks. The new 3UL discharge system was to be designed to allow bulk material to be discharged from ship directly into trucks on the berth under 3UL, or onto an existing berth conveyor, and be capable of handling multiple bulk material types including iron ore lumps/pellets, coal, limestone and dolomite with varying bulk density and flowability.
What we did:
- Performed bulk material flow/structural assessment (via FEA and DEM simulation) of the discharge hopper, transfer conveyor, berth conveyor/truck loading discharge chutes and platform structure (including equipment support frames and considering vibratory feeder operating parameters) considering transport, installation and operation.
- Designed a transfer conveyor system including head/tail pulleys (including belt tensioning system), idlers, bearings, primary/secondary scrapers, belt, drive components (i.e. gearmotor, coupling), frame, guards/skirting, spill trays and load cells.
- Designed a berth conveyor/truck loading discharge chute system including hood/spoon, chutes and spoon/isolation gate drives (i.e. gearmotors, slewing drives).
- Modelled the discharge system equipment (for engineering/detail drawing development).
Outcome:
Avesta Consulting successfully designed a new 3UL discharge system, including discharge hopper, vibratory feeders, transfer conveyor, platform structure, vibratory feeder support frame, berth conveyor/truck loading discharge chutes and spoon frame, which achieved the design criteria and could meet the performance requirements specified by CLIP.
