thyssenkrupp to supply gyratory crusher to Roy Hill iron ore mine

Thyssenkrupp has been awarded a contract to supply a new primary jaw gyratory crusher for the Roy Hill iron ore Mine in Western Australia. Located 340 kilometres south-east of Port Hedland, Roy Hill is a world-class iron ore operation with an integrated mine, rail and port facilities producing 55 million tonnes per annum, with approval to increase to 60 million tonnes.

The new crusher is the first above ground jaw gyratory crusher to be installed in Australia. It will be designed for high performance and cost-effective operation, i.e. low servicing and maintenance costs.

“We are excited and grateful for the opportunity to be supplying Roy Hill with a new primary jaw gyratory crusher,” said Ben Suda, head of sales at thyssenkrupp Industrial Solutions (Australia). “This is the third order for such machine within a short time in Australia. It shows once again the confidence our customers in the country place in crushing equipment from

The jaw gyratory crusher is characterized by an especially enlarged feed opening. It is normally serrated 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

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.

Metso to supply equipment to De Beers’ Venetia diamond mine

Metso Corporation will deliver high-performance crushing and material handling equipment to the De Beers Group Venetia mine, in Limpopo Province, South Africa. The Venetia mine is reported to produce an output of about 4 million carats, making it one of South Africa’s mineral resource flagships.

The Venetia mine was initially designed as an open-pit operation. In 2013, an underground extension project commenced with plans to start producing carats in 2022, climbing to full production in 2025 and extending the mine life to 2046. Metso will deliver two primary jaw crushers and a number of feeders. All the equipment will be installed underground, a challenging installation given the shaft constraints and weight limitations for transportation underground.

The Metso apron feeders are used for extracting or feeding ores that are wet, sticky, dry or even frozen. Jaw crushers are ideal for tight spaces, such as underground mining and mobile crushing applications.

The design of Metso’s Nordberg C Series jaw crusher allows for the extensive disassembly, aiding transportation and installation, especially where there are critical space constraints such as an underground installation.
