Weir has released a report detailing how high pressure grinding rolls and digital monitoring systems can lower energy use in mining. This analysis explores how comminution, the process of crushing and grinding rock, affects overall site power consumption.
Why it matters
These technological advancements are intended to help the mining sector control operating costs while working toward carbon emission targets. The report highlights how better equipment integration influences energy efficiency in mineral processing.
High pressure grinding rolls achieve an energy intensity reduction of 5kWh per tonne when compared to traditional crushing methods. Weir also deploys the ETX exciter technology for particle separation and the NEXT Intelligent Solutions digital platform to monitor equipment performance.
The players
Weir
An engineering company that manufactures primary and secondary crushers and high pressure grinding rolls for the mining industry.
The details
Comminution—the breaking down of ore into finer particles—is a primary energy consumer in mining. Weir achieves these efficiency gains by ensuring that crushing and screening circuits operate sequentially. This precise classification of materials minimizes the rehandling of rocks that have already reached the required size.

The Tech Race
The mining industry is currently navigating a shift toward low-energy processing to meet its global carbon emission goals. Weir is positioning its equipment portfolio against established legacy infrastructure to gain market share in the transition to more sustainable mineral extraction.
Mining operators and process engineers can now evaluate these efficiency gains when planning equipment upgrades or site retrofits. These technologies primarily change the workflow of crushing and screening circuits to reduce power consumption during the primary mineral reduction phases.
The takeaway
Advancements in comminution technology illustrate the ongoing efforts to minimize energy consumption in heavy industry. Operators should monitor future benchmark reports to see how these efficiency gains translate to site-level operational savings.
