thyssenkrupp Industrial Solutions Australia awarded supply of World’s first “double mouth” jaw-gyratory crusher for CMOC-Northparkes Mines (Northparkes) in New South Wales.
- World’s first “double mouth” jaw-gyratory crusher to be sold
- Demonstrates thyssenkrupp’s continuing commitment to crusher innovation following the recent release at Bauma of the Eccentric Roll Crusher, ERC, (with particularly flat and robust design and high throughputs), the modular Variopactor impact crusher (designed for use in small and medium size quarries) and the KB 63-130 gyratory (the world’s highest capacity primary crusher).
thyssenkrupp Industrial Solutions Australia has recently signed a contract with Northparkes in New South Wales. Northparkes is a metalliferous underground mine located approximately 27km northwest of Parkes in the Central West, New South Wales. Northparkes began mining at the site in November 1993 with the company now processing approximately 6.4M tonnes of ore per annum of high-grade copper-gold concentrate, which is shipped to its clients overseas for smelting.
Mr Ben Suda, Head of Sales at thyssenkrupp Industrial Solutions Australia: “What makes this order significant is that this will be the first “double-mouth” jaw-gyratory crusher supplied in the World.”
The new Double Mouth Jaw-Gyratory Crusher has been developed in consultation with Northparkes to meet their very specific operating objectives. 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.
thyssenkrupp have supplied over 250 gyratory crushers throughout the world, and are at the forefront of machine design and operation, with seven (7) standard indirect fed jaw gyratory crushers installed in Australia alone. thyssenkrupp has establishedservice facilities throughout Australia to support its valued customers.
Northparkes was the first mine to use the standard indirect fed Jaw Gyratory crusher type BK 63-75 for their newly developed block caving mine concept. This primary crusher design has become the “state of the art” solution for block caving mines.
Mr Ian Smith, Engineering Superintendent of the E26L1N Block Case Mine Project at Northparkes Mines: “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. We are looking forward to the new DBK 63-75 being commissioned.
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 ROM bin and primary feeder thus reducing the mass excavation underground. Also the ability of this crusher to handle a very large feed size and a high reduction ratio has negated the need for the use of a pre-screening grizzly.
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.”
