Weir Minerals continues to make inroads in the comminution market, with the company having achieved a major high pressure grinding roll (HPGR) milestone during 2023, Weir Group’s 2023 financial year results confirmed.

In a Weir Group report that highlighted flat year-on-year orders and a 16% increase in adjusted profit, the Minerals division noted a significant increase in its aftermarket solutions.

“This reflects growth in our installed base, and our increased strategic focus on this area,” Weir Group said in the results. “A particular highlight was an order from a large copper mine in South America, where our customer ordered Enduron® rollers for their HPGR.”

The installation will be the first instance of Weir Minerals’ rollers being fitted to a competitor’s HPGR, enabling the company to showcase the performance and reliability benefits of its technology, it said.

It concluded on this area: “More generally, the pipeline for our HPGR remains strong with a number of projects advancing materially throughout the year.”

Weir Minerals says the Enduron HPGR is a market proven model with the mechanical design to support efficient and durable skewing thanks to its unique bearing arrangement and control philosophy. It has a unique roll diameter-width ratio, which maximises throughput at the desired product grind. Self-adjusting cheek plates provide equal sealing distance as flanges at minimum costs, according to the OEM.

Alongside this, Weir Minerals also gained further market share in 2023 in mill circuit pumps, converting over 85% of its competitive field trials.
