    Metso’s €10m Vertimill 4500 order: grinding efficiency lens for DR iron ore engineers

    First reported on International Mining – News

    30 Second Briefing

    Metso has secured an order worth over €10 million for multiple Vertimill® 4500 grinding mills for a Direct Reduction (DR) grade iron ore project, targeting finely ground feed suitable for DR pelletising. The vertical stirred mills are designed to cut specific energy consumption and operating costs compared with conventional ball mills, aided by a smaller installation footprint and reduced media usage. For process engineers, the choice of Vertimill 4500 units signals a push towards higher grinding efficiency and tighter particle size control in DR-grade iron ore circuits.

    Technical Brief

    • Vertical stirred mill geometry enables higher power intensity per footprint than comparable horizontal tumbling mills.
    • Reduced grinding media consumption in Vertimill® circuits directly lowers steel make-up and handling requirements.
    • Smaller concrete and structural steel quantities are implied by the compact vertical mill foundations.
    • Finer grind capability supports narrow PSD control needed ahead of DR pelletising induration and reduction.
    • Lower specific energy draw eases electrical infrastructure sizing for greenfield DR pellet feed plants.

    Our Take

    In our database of 1064 Mining stories, Metso features frequently in higher‑value processing contracts, and this >€10 million Vertimill 4500 order aligns with a pattern of the company securing large, technology‑heavy packages rather than smaller, stand‑alone equipment sales.

    Recent coverage of Metso’s acquisition of MRA Automation (2 February 2026) suggests that big mill orders like this DR‑grade iron ore installation are likely to be paired with more integrated automation and control offerings, tightening Metso’s grip on whole‑of‑circuit performance guarantees.

    The combination of this Vertimill order with Metso’s “whole‑of‑circuit” push highlighted on 11 February 2026 indicates that iron ore clients are increasingly buying into energy‑efficient grinding as part of broader sustainability and DR‑grade quality strategies, not just as a bolt‑on equipment upgrade.

    Thiess adds fourth Liebherr R 9800 at Lake Vermont: fleet and productivity notes for engineers

    Thiess has mobilised a fourth Liebherr R 9800 hydraulic excavator to Jellinbah Group’s Lake Vermont coal mine in Queensland, expanding a fleet already built around ultra-class loading units. The R 9800, typically paired with 220–300 t class haul trucks and capable of 40–80 m³ bucket capacities depending on configuration, is being deployed to meet rising production requirements and tighten truck–shovel match. The move signals continued capital commitment to high‑productivity primary loading assets and supports longer-term planning for efficient strip mining and overburden removal.

    Finning–McCloskey 10,000th Cat engine: fleet planning notes for plant engineers

    Finning UK & Ireland has supplied its 10,000th Cat® industrial engine to McCloskey International, extending a supply partnership that began in 2006 when McCloskey established manufacturing in Northern Ireland. The engines power McCloskey’s mobile crushing, screening and material handling equipment, which is seeing rising global demand in aggregates and mining applications. For plant operators, the milestone signals long-term parts and service continuity for Cat-powered McCloskey units, an important factor in lifecycle planning and fleet standardisation.

    Glencore Sudbury INO mine rescue win: training takeaways for deep nickel operations

    Glencore’s Sudbury Integrated Nickel Operations (INO) mine rescue team has taken the 2026 Ontario Mine Rescue overall champion title in Sudbury, outperforming seven other regional winners in a province-wide final. The team completed a complex mock underground emergency scenario designed by Ontario Mine Rescue (OMR), typically involving live-fire suppression, casualty extrication and use of closed-circuit breathing apparatus under time and communication constraints. For mine operators, the result reinforces the value of rigorous, scenario-based training regimes and standardised emergency procedures across multi-level, deep nickel operations.
