thyssenkrupp is to make history in Australia, with plans to install KB 63-130 type gyratory crushers at the jointly owned Iron Bridge magnetite project, in Western Australia.

The company said its mining business unit had been awarded consecutive contracts to supply these two gyratory crushers and a radial stacker for Iron Bridge, which is a joint venture between Fortescue Metals Group subsidiary FMG Iron Bridge and Formosa Steel IB Pty Ltd.

Iron Bridge will be a new magnetite mine, around 145 km south of Port Hedland in the Pilbara region of Western Australia. Delivery of first ore is scheduled for mid-2022.

Johann Rinnhofer, CEO of thyssenkrupp’s mining business in Australia, said: “We are proud to be part of this project and excited to install two of thyssenkrupp’s next generation gyratory crushers here in Western Australia. These high capacity crushers are considered to be the largest and most powerful in the world and are unrivalled when it comes to crushing blasted hard rock and ore.”

The KB 63-130 type gyratory crushers will be the largest ever installed in Australia, according to thyssenkrupp, with the crushers processing raw iron ore material from the pit and transfering it to a receiving conveyor.

The slewing and luffing radial stacker, meanwhile, will be used to stack secondary crushed magnetite iron ore onto a stockpile at the mine.

The Iron Bridge project will deliver 22 Mt/y (wet) of high grade 67% Fe magnetite concentrate product, according to FMG.

The first stage of the project was completed successfully by building and operating a full-scale pilot plant at the North Star mine site. This pilot project included the use of a dry crushing and grinding circuit, which FMG plans to leverage in stage two.

The second stage of the project comprises the construction of a large-scale process plant, and port
infrastructure to support the production of 22 Mt/y (wet).
