One of the more than 250 thyssenkrupp gyratory crushers around the world in Sweden.

Thyssenkrupp Industrial Solutions continues to strengthen its place as a leading manufacturer and supplier of gyratory crushers for the Australian mining market.

The company finished off 2019 by winning a contract to supply a new primary jaw gyratory crusher for the Roy Hill iron ore mine in the Pilbara, Western Australia.

Its third order in 12 months, the thyssenkrupp product is also the first above ground jaw gyratory crusher to be installed in Australia.

The crusher has been designed for both high performance and cost-effective operation, providing Roy Hill with low servicing and maintenance costs.

thyssenkrupp Industrial Solutions Australia head of sales Ben Suda says the order once again shows the confidence the Australian mining industry places in the company’s crushing equipment.

“The jaw gyratory crusher is characterised by an especially large feed opening,” Suda says. “It is normally serrated out and, together with the upper part of the mantle, forms the initial crushing zone.

“The coarsely crushed material is then reduced to the desired product size in the crushing chamber below.”

Jaw gyratory crushers can handle much bigger chunks of material than comparable gyratory crushers of the same mantle diameter and feature a higher crushing ratio, with less tendency to become clogged in the feed zone as a result of bridging, Suda adds.

After a strong 2019, thyssenkrupp has nine jaw gyratory crushers operating in the Australian mining industry.

Australia has emerged as a key growth market for the company’s gyratory crushers, adding to the more than 250 systems around the world.

thyssenkrupp remains the only supplier of the jaw gyratory crusher and has left its mark in multiple applications, from coarse feed material sites to block cave mines and underground operations.

Northparkes in New South Wales, for example, was the first mine to use the standard indirect fed jaw gyratory crusher, type BK 63-75, for a block cave mine.

Since the Northparkes installation, the primary crusher design has become the standout solution for block cave mines taking run-of-mine ore extracted using this advanced method.

Block caving has proven to be cost effective but often delivers a relatively coarse run-of-mine material with unpredictable maximum lump size, which can be effectively crushed using the jaw gyratory system.

Gyratory and jaw type gyratory crushers are more broadly an integral part of semi-mobile and stationary processing plants used for primary crushing of bulk materials in ore mines and the natural rock industry. 

thyssenkrupp’s design of the crushers, based on more than 100 years of experience, represents state-of-the-art engineering design and 3D software capabilities.

The crushers are designed for both high throughput rates and large crushing ratios, while minimising operating and maintenance costs.

thyssenkrupp has taken a versatile approach with the crusher design, including the option for complete top service or bottom service machines.

Suda says an added benefit is the ability to operate the crusher remotely or locally using the Gyromatic control system.

“The innovative jaw gyratory crusher is a unique concept based on the proven and widely used standard gyratory crusher,” Suda says.

“Jaw gyratory crushers combine the advantages of both common jaw and gyratory crushers and are used worldwide for the crushing of ores, natural rock and limestone in applications with extra-large feed material.”

thyssenkrupp has developed the jaw gyratory crusher with a three-piece crusher shell, incorporating a bottom shell, middle shell and spider with extended crusher throat, providing the large feed opening.

The main shaft features an integrated lifting lug for direct attachment onto the crane hook, while a self-tightening head nut ensures the proper securing of the manganese mantle.

thyssenkrupp has fitted the eccentric bush assembly with a balance weight for reduction of horizontal foundation forces. The optional top service configuration further reduces these forces.

These proven design characteristics, combined with a growing track record in the Australian marketplace, have the thyssenkrupp jaw gyratory crusher ready for another exciting year in 2020.
