Primary Crushed Ore – Transfer Chute Design
Material: Iron Ore
Solution: StallFlow Chute and SmartFlow Deflector
The particular chute allowed for PC Ore (-300mm) at 2,800tph. This improved wear control and operational performance. The StallFlow Chute and SmartFlow Deflector introduced soft loading, increasing belt life, minimising dust/spillage and removed frequent belt damage issues on the receiving belt.
Key performance features of Gulf’s transfer chute include:
- Throughput increased >3,500 tph
- No blockages under design operating conditions
- Lowered drop height from 8m down to 4m
- SmartFlow deflector like 84 weeks before ceramic re-line
- Chute maintenance interval >40 weeks – selected components only
- Client’s first application of a ceramic lined deflector for primary crushed ore
- Central loading and belt tracking
- Increased belt life of receiving belt – reduced punctures
Fines Ore – Transfer Station
Material: Iron Ore
Solution: StallFlow Chute and SmartFlow Deflector
The particular chute allows for fine wet-sticky material (-8mm) at 16,000tph. This provided a significantly improved surcharge angle on receiving belt compared with previous chute and in addition to higher volumes of ore through the chute. Increased maintenance shutdowns in excess of 52 weeks, both for chute and deflector.
Key performance features are summarised below:
- Consistent throughput at >15,000 tph
- Capability to handle various products including unwashed fines, washed fines, wet fines and dry fines
- No blockages under design operating conditions
- 57 weeks until first chute repair – replacement of 2 panels only
- Belt top cover wear reduced by 20%
- Chute MTTR 48 hours
- SmartFlow deflector life 152 weeks
Optimum surcharge angle onto receiving belt (>25°), when compared to adjacent ceramic lined chute (same operating parameters)
ROM Ore – Shuttle Deflector & Chute Transfer Design
Material: Iron Ore
Solution: StallFlow Chute and SmartFlow Deflector
The particular chute allowed for ROM Ore (-250mm) at 9,500tph. A SmartFlow Deflector was installed to feed both screens and scrubbers. A right angled StallFlow Chute was also installed to remove prominent belt rips.
Primary Crushed Ore – Transfer Chute Design
Solution: StallFlow Chute and SmartFlow Deflector
The particular chute allows for Primary Crushed Ore (-200mm) at 2,500tph.
Lump Ore – Transfer Chute Design
Material: Iron Ore
Solution: StallFlow Chute and SmartFlow Deflector
Gulf provided full design services and on-going technical support for the Transfer Chute project. The particular chute allows for lump material (-32mm) at >6,500tph. Previous chute rebuild time was every 12 weeks. Gulf technology allowed a current maintenance interval time >52 weeks.
This provided:
- Spoon sample cutter installed in head chute
- Flow & wear control achieved using StallFlow technology
- Ceramic lined SmartFlow deflector, providing optimum flow
- Independent scrapings chute
- Cassette modular style rotable maintenance system
- Hard skirts eliminated as part of Gulf design
