Project Background
Engineering, procurement and construction for upgrades to increase the capacity of the fines circuit of the Main Plant to achieve a whole plant average of 1,350 TPH.
The fines circuit capacity of the current 4th module coal preparation plant was increased to an equivalent whole plant feed rate of 650 tph without compromising the current efficiency.
The upgrade included the installation of a product thrower on the end of the existing 17M product conveyor.
The upgrade of Main Plant was to achieve an average equivalent whole plant target throughput of 1350 TPH through the fines plant:
- All major fines circuit pump capacities including clarified water
- Jameson Cell capacity clean coal and desliming cyclone capacities
- Spiral product dewatering capacity
- All major fines circuit pipeline sizes
- Modification of the spirals tailings dewatering system
The upgrade of the 4th Module was to achieve an average equivalent whole plant target throughput of 650 TPH through the fines plant. This was achieved through the following key changes:
- Upgrade of 4AM conveyor
- Additional 2 desliming cyclones and 3 spiral product cyclones
- Installation of a new bank of 8 triple start spirals
- Installation of 2 fine coal centrifuges
- Installation of larger spiral rejects screen
- Pipework, collection and distribution boxes associated with the above circuits
- Pumps, pipework and other equipment outside the above circuits necessary to achieve the performance tests
- Electrical installation and controls upgrade
