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).

thyssenkrupp and Northparkes collaborate on latest crushing innovation

thyssenkrupp Industrial Solutions Australia says it recently signed a contract that will see the world’s first “double-mouth” jaw-gyratory crusher supplied to China Molybdenum majority-owned Northparkes underground copper-gold mine in New South Wales.

The new crusher has been developed in consultation with Northparkes to meet its specific operating objectives, according to thyssenkrupp.

The company explained: “This unique jaw-gyratory crusher is a modern machine based on the proven BK 63-75 design. thyssenkrupp has developed a new, patented, spider to give the opportunity to feed the crusher from both sides – the “double mouth” jaw configuration, thus removing the need for a primary crusher feed (buffer) hopper and primary apron feeder.”

This dramatically reduces excavation requirements in an underground operation like Northparkes leading to a sizeable reduction in installation cost, according to thyssenkrupp.

The delivery of this latest crushing innovation follows the recent release of the company’s Eccentric Roll Crusher, the modular Variopactor impact crusher and the KB 63-130 gyratory crusher, the company said.

Northparkes is one of the most modern underground block cave mines in the world, with the majority of its loading and haulage operations carried out autonomously. Mining started up at Northparkes in November 1993, with 80% owner China Molybdenum now processing around 6.4 Mt/y of ore of high-grade copper-gold concentrate, which is shipped to its clients overseas for smelting.

Northparkes was the first mine to use the standard indirect fed Jaw Gyratory crusher type BK 63-75 for its newly developed block caving mine concept, thyssenkrupp said, with this primary crusher design becoming the “state of the art solution for block caving mines”.

Ian Smith, Engineering Superintendent of the E26L1N Block Cave Mine project at Northparkes, said: “As a long-time owner, operator and maintainer of the thyssenkrupp jaw gyratory crushers for primary crushing underground, Northparkes is pleased to be installing its third BK 63-75 in the new E26L1N block cave mine underground crusher station.

“The first BK 63-75 crusher of its kind was commissioned underground at Northparkes in 2003 followed by a second installation in 2009. Northparkes has worked closely with thyssenkrupp over the years to develop and make improvements to these crushers and has developed great confidence in the reliability and robustness of the BK 63-75 crusher.”

Smith said the first two crushers installed are of a single mouth design with the latest crusher being a double mouth design that is “ideal for our direct tip underground crushing station dump pocket that negates the use of a large run of mine bin and primary feeder thus reducing the mass excavation underground”. He said the ability of this crusher to handle a very large feed size and a high reduction ratio has also negated the need for the use of a pre-screening grizzly.

He concluded: “Northparkes’ innovative culture is again highlighted as shown in their initiation and involvement in the development of the double mouth feed shell with thyssenkrupp with the aim that the performance of this crusher will not only meet but will exceed expectations.”
