Iron Ore Mining Exploration Activities in Australia

Four giant in-pit crushers are taking shape at Citic Pacific mining ‘s Sino Iron project at Cape Preston in north west WA. They may be becoming manufactured by ThyssenKrupp, with components getting fabricated in Australia, Germany and China.

In terms of installation progress, a spokesman from owner Citic Pacific Mining (CPM) told the AJM in mid- February that “the first two of 4 crusher pocket slots are completed as well as the first in-pit crusher is becoming installed. The bucket wheel reclaimer installation is pretty much completed.

“In terms of start off up date, the initial shipment of ore is anticipated towards the latter component of this year.”

The in-pit crushers supplied will probably be gyratory, 60″ x 89″, using a capacity of 5,100 tph. They’ll be powered electrically by the project’s combined-cycle gas-fired power station and have been integrated into the mine style.

A number of other aspects were taken into consideration throughout the style phase, such as the rigidity in the conveyors, energy needs resulting from the depth from the pit, the layout of the infrastructure, the width in the haul road and site visitors management desires.

CPM deputy director operations Andrew Thomson said progressive run-of-mine pads and conveyor paths had been designed into the pit. “When ready the crushers are un-coupled and moved towards the new location employing crawler units. They may be effectively ‘plug and play’ installations and though it is a significant task it can be much less onerous than a fixed installation,” Mr Thomson stated.

After blasting, the crushers are fed by a truck and shovel combination. The 200 millimetre crushed ore is then transported by big conveyors for the coarse ore stockpile at the feed end with the concentrator.

ThyssenKrupp invented mobile crushing technologies in 1956 and also the firm is at this time a leader in in-pit crushing systems, getting supplied more than 200 globally.

A senior processing engineer from ThyssenKrupp Supplies Handling spoke for the Australian Society for Bulk Solids Handling (ASBSH) in February in Perth concerning the company’s technologies within the region. Christoph Hoetzel’s session was entitled “the evolution and outlook for ThyssenKrupp’s substantial scale semi-mobile crushing plants.”

“There were at the very least 40 men and women in attendance and it was an excellent presentation,” stated Eric Lau, lead mechanical engineer, AMEC Minproc and WA technical convener.

Christoph’s speech was a joint technical session presented by the Mechanical Branch Engineers Australia WA, the Institution of Mechanical Engineers, the American Society of Mechanical Engineers and the ASBSH.

As the professional manufacturer of complete sets of mining machinery, such as impact breaker,Mobile jaw crushers, Henan Hongxing is always doing the best in products and service.
