Product:
Alumina Bath Slag
Requirements of Comalco
Comalco requested Aerobelt prepare a solution for conveyors in the Alumina processing plant. They were required to carry bath slag that being recycled within the manufacturing process.
The conveyor had to:
- Be able to cater for product temperatures to 135°C.
- Minimise the capital cost of the support steelwork.
Technical Information
- Conveyors: 3
- Belt Width: 500 mm
- Length: 99 m
- Inclination: 17°
- Capacity: 90 tph
- Belt Speed: 1.6 m/s
- Drive Power: 7.5 kW
- Fan Power: 4 kW
- Product Density: 1.9 T/m³
Aerobelt Solution
Aerobelt selected a 500mm belt conveyor with a Nitrile belt to transfer product out of the plant.
At this point, new material was added to the slag to enable all the material to be re-used.
A third conveyor at another higher elevation filled storage silos which were used to load trucks that delivered the replenished raw material back into the plant.
The specially constructed sections used supporting locations spaced at large distances to minimise costs.
