MAWSONS Quarry at Pyramid Hill, Victoria, has become the first quarry in Australia to commission Industrial Conveying (ICA) radial stacker technology to replace standard conveyor systems.
This five-day operation processes between 200-300 tph of road base and cement bound for roads servicing.
The quarry not only reduced shutdown and maintenance costs by instituting radial stackers, it also solved some of the dust problems that could not be overcome with standard conveyors.
The solution from ICA engineers included two combined radial and luffing stackers, one automated luffing unit, and a straight out radial stacker as well as significant screen adjustments, stands and chute work.
The ICA radial stacker system is predominantly used in the primary scalping section. At the primary scalping section, the system scalps 16mm- and 9-inch+ plus product, with the primary running over a 14 x 5 horizontal screen.
Any product 180mm+ goes off to one stacker, anything between 180mm and 18mm to a separate conveyor belt, and anything under 18mm off to another radial stacker. Throughput can be as much as 2000 tph depending on how wide a belt is fitted. Only a reasonably smooth surface is required on which to operate.
Available to work on standard truck tyres or aircraft tyres, the ICA radial stacker can be hydraulic- or electric-driven (including the belt).
