thyssenkrupp is to install the first above ground jaw gyratory crusher in Australia at the Roy Hill iron ore mine, in the Pilbara of Western Australia, following an agreement signed with the mining company.

Located 340 km southeast of Port Hedland, Roy Hill has integrated mine, rail and port facilities and produces 55 Mt/y of iron ore, with approval to increase to 60 Mt/y.

The new crusher will be designed for high performance and cost-effective operation, ie low servicing and maintenance costs, according to thyssenkrupp.

Ben Suda, Head of Sales at thyssenkrupp Industrial Solutions (Australia), said: “We are excited and grateful for the opportunity to be supplying Roy Hill with a new primary jaw gyratory crusher. 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 thyssenkrupp.”

The jaw gyratory crusher is characterised by an especially enlarged feed opening, according to thyssenkrupp. 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 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, the company concluded.
