Metso and Loesche Unveil VRM Dry Grinding Solution

Why It Matters

Comminution accounts for a large share of mining energy and emissions; a more efficient, dry‑grinding option directly improves profitability and sustainability across the sector.

Key Takeaways

• VRM dry grinding cuts energy use dramatically
• Simplifies flowsheets, replacing HPGR and horizontal mills
• Improves particle size consistency, limits sulphide oxidation
• Enables dry processing, reducing water consumption
• Over 2,400 VRM references prove reliability across industries

Pulse Analysis

The mining industry’s biggest energy drain remains comminution, where traditional crushers and mills consume up to 30 % of a plant’s power. By leveraging Loesche’s proven VRM platform and Metso’s end‑to‑end processing expertise, the new dry‑grinding solution offers a lower‑energy alternative that can be retrofitted into existing circuits. The partnership’s focus on advanced wear‑resistant liners and real‑time process control not only trims electricity bills but also reduces the frequency of maintenance shutdowns, delivering a clear operational advantage.

Beyond energy, the VRM system supports a shift toward fully dry processing, a growing priority as water scarcity intensifies in key mining regions. The technology’s ability to produce a steeper, more uniform particle‑size distribution improves downstream flotation and magnetic separation, while limiting oxidation of sulphide minerals preserves valuable metal content. These benefits align with emerging coarse‑beneficiation flowsheets that aim to cut water usage and chemical reagents, reinforcing the sustainability narrative.

Market implications are significant. With over 2,400 VRM installations in cement and other sectors, the technology brings a track record that mitigates adoption risk for miners. Metso’s exclusive distribution through its Metso Plus portfolio ensures integrated support and financing options, accelerating deployment. As mining companies chase lower carbon footprints and tighter margins, the Metso‑Loesche VRM dry‑grinding solution is poised to become a benchmark for next‑generation, resource‑efficient comminution.
