Weir Minerals has announced a major order of its Enduron HPGR (high pressure grinding roll) from IAMGOLD.

An Enduron HPGR with rolls measuring 2.4 metres x 2.4 metres (length : diameter) will be installed at IAMGOLD’s CôtéGold project.

This will be the largest HPGR in Canada and the largest in the world in a gold hard rock application.

Weir Minerals’ Enduron HPGR unique design is perfectly suited to IAMGOLD’s Côté Gold operations to achieve industry-leading particle size reduction and with the lowest total operating costs.

Enduron HPGR is the market proven HPGR with the mechanical design to support efficient and durable skewing thanks to its unique bearing arrangement and control philosophy
Enduron HPGR has a unique roll diameter-width ratio which maximizes throughput at the desired product grind
Enduron HPGR self-adjusting cheek plates provide equal sealing distance as flanges at minimum costs
Enduron HPGR is the market leader in large format, high tonnage hard rock HPGR


“Our Enduron HPGR design will create energy savings of up to 40% compared to an equivalent SABC (semi-autogenous ball mill crusher) comminution circuit, while also significantly reducing the need for downstream grinding media,” HPGR regional sales manager North America Tim Lundquist said.

“This power and grinding media savings will optimize total ownership cost and also account for a significant reduction in carbon emissions”.

The Weir Minerals Canada team and purpose-built facilities will be providing full HPGR service for the Côté Gold operations.
