Powermaster’s mineral processing Revolution continues with latest tech demo
Almost 18 months after the launch of its high-speed vertical attrition system, the Revolution, Powermaster is reporting that it has completed a performance demonstration for a top-10 global mining company, validating its ability to process granite rock at industrial scale while delivering measurable efficiency gains in energy use, throughput and circuit simplification.
During the trial, the Revolution micronised granite, achieving 80% passing 45 µm from rock sizes up to 24 in (610 mm) in a single continuous pass. The system’s throughput matched Powermaster’s scalable target of up to 300 tons (272 tonnes) per hour, confirming its potential to replace conventional multi-stage crushing and grinding circuits in hard-rock operations, the company says.
A Senior Process Engineer from the mining company in question said: “Based on the energy and throughput we saw, the Revolution is saving us a little over 20% compared to our current comminution setup.”
These results align with Powermaster’s field data showing that the Revolution consistently delivers a verified minimum of 20% reduction in comminution costs, along with lower water demand, reduced energy use and improved downstream recovery efficiency.
Powermaster Founder, Haiku York, added: “Granite is one of the toughest materials in the industry, and the Revolution handled it in a single pass. Achieving 80% under 45 microns at scalable throughput shows that this technology is ready to change how the world processes material.”
Powermaster says it is preparing additional blind case studies and full-scale demonstrations as the Revolution moves toward broad commercial deployment, noting interest from major producers across the copper, gold, aggregates and industrial minerals sectors.
