FLS vertical mills: design and energy-efficiency notes for plant engineers
Reviewed by Tom Sullivan

30 Second Briefing
FLS is advancing its vertical media regrind mills, with Global Product Line Manager Peter Wulff emphasising attrition-based grinding that delivers finer particle sizes at lower specific energy than conventional ball mills. The latest designs integrate high-efficiency drives and advanced process control to cut CO₂ emissions per tonne milled, targeting operations dealing with lower head grades and higher hardness ores. For plant designers, this points to smaller footprint regrind circuits, reduced steel media consumption and improved liberation for downstream flotation.
Technical Brief
- Vertical regrind mills are positioned in the fine grinding duty, downstream of primary and secondary milling.
- Design focus is on maximising metal recovery in regrind applications rather than primary throughput capacity.
- In an era of declining grades, OEMs like FLS are re-optimising comminution flowsheets around regrind performance.
Our Take
FLS’s push on vertical mills for decarbonisation sits alongside its recent comminution wins in copper and iron ore – our coverage shows the company increasingly anchoring flowsheet designs around its own crushers, mills and sizers rather than just supplying standalone units.
The new Mackay service centre in the Bowen Basin, combined with energy‑efficient vertical mills, signals FLS is betting on lifecycle performance contracts where reduced power draw and faster shutdowns become part of the commercial offer to coal and bulk‑commodity operators.
Across the 2064 tag‑matched ‘Projects/Product/Sustainability’ pieces in our database, FLS is one of the few OEMs appearing repeatedly in both technology launches and project awards, suggesting miners view its grinding and crushing kit as a primary lever for meeting Scope 1 power‑related targets.
