Independent Benchmark Confirms MicroMill Delivers Upto 84% Lower Energy Use Than Conventional Ball Mills

Aquagen Energy Ltd announces results from a head-to-head technical comparison against
an industry-standard reference ball mill - confirming a step-change in grinding efficiency,
media wear, and equipment footprint.
Birmingham, UK — May 2026. Aquagen Energy Ltd, the British clean-technology
company developing the MicroMill precision micronisation platform, today released the
results of an independent technical benchmark comparing MicroMill against a conventional
industry-standard ball mill of equivalent productivity.
The findings, drawn from published manufacturer specifications and engineering data,
confirm what the company has long maintained: that 200-year-old grinding technology is
no longer fit for the energy economics or the regulatory environment of the modern
industrial sector.
The headline numbers
At equivalent throughput — both systems benchmarked in the 16 to 29 tonne-per-hour
range - MicroMill delivers:
Up to 84% lower specific energy consumption (5–8 kWh/m³ versus 30–50 kWh/m³)
A 79% reduction in motor power draw (100 kW versus 475 kW)
Approximately 46 times lower grinding-media wear (~12 g/tonne versus ~550 g/tonne)
A 55% reduction in equipment weight (25 tonnes versus 56 tonnes)
A finer, more consistent particle output (10–80 microns versus 75–400 microns)
The most fundamental difference, however, is structural. The reference ball mill requires
89 tonnes of steel grinding media to operate. MicroMill uses none.
What this means for the industry
For the heavy industrial sectors that depend on grinding - cement, steel, metals, minerals
- the implications are significant. The cement industry alone accounts for roughly 8% of
global CO₂ emissions, with conventional clinker grinding contributing a substantial share of
that footprint. A grinding technology that uses a fraction of the energy, generates virtually
no media-borne contamination, and occupies less than half the footprint of the equipment
it replaces represents a credible decarbonisation pathway for one of the world's hardest-to-
abate sectors.
For pharmaceutical, food-grade, and high-purity metals processing, the absence of
grinding media changes what is commercially possible. Markets that conventional ball mills
cannot serve - because of contamination, particle inconsistency, or cleaning-validation
barriers - become directly addressable.
A different engineering principle
MicroMill achieves these results because it is not a refinement of conventional grinding. It
is a different mechanism. Material enters a high-speed rotating chamber and passes
between a precision roller and grinding track, with a blade system continuously lifting and
recirculating material through the grinding zone - 150-plus passes per cycle, completed
in seconds. No tumbling steel. No media wear. No contamination transfer.
The platform is currently available in two configurations: MicroMill Titan for heavy
industrial applications, and MicroMill Pura for pharmaceutical and medical-grade
processing.
Looking ahead
Aquagen Energy is now progressing toward pilot-scale demonstration of the Titan
configuration in UK industrial settings, with grant-supported deployment programmes
under development. The company is engaging with cement, metals, and minerals
operators across the UK, Europe, and beyond.
"The benchmark confirms what our engineering team has been demonstrating in the lab"
said Dilaawar-Abbas Bukhari, CMO and Co-Founder of Aquagen Energy. "Industrial
grinding has not been seriously challenged in two centuries. We've challenged it. The
numbers speak for themselves."
