Enerpac said its strand lift system, capable of safely positioning huge loads to accuracy, is being used to construct the Sino iron ore project, Australia’s largest-ever magnetite mining and processing operation.
The project, owned by China Metallurgical, features 12 iron ore processing mills manufactured in China. These were transported in sub-assembly form for precision positioning onto their bearings 21m above the ground.
The VDM Group will use the Enerpac precision lifting technology to install initial six pairs of 800 tonne ball mills and 1,400 tonne autogenous mills where access is restricted, overhead space is limited or maximum stability is required.
The Sino Iron Ore Strand Lift System involves four 444 tonne 37 Strand, Strand Jacks with Recoiler and Palm Tree Control Systems positioned on the prefabricated steel structures above the position.
The ball malls are delivered by road to the mill site at the Cape Preston concentrator area in Western Australia’s far northwest.
The mobile transporter then transports the mills laterally to a position adjacent to the foundation towers on which the trunnion bearings are located, where the Strand Lift System operating from another prefabricated jacking towers lifts and lowers them into their final position.
The Sino project has two billion tonnes of magnetite ore and will process 27.6 million tonnes a year of a mix of pellets and concentrate.
