    Metso Grande Series screening: flowsheet and uptime gains for plant engineers

    Metso Grande Series screening: flowsheet and uptime gains for plant engineers

    First reported on Australian Mining

    30 Second Briefing

    Metso has launched its Grande Series of high-performance mining screens, engineered for heavy-duty classification in large-capacity crushing and screening circuits. The range targets high-throughput operations with optimised stroke, speed and deck configurations to increase screening efficiency and uptime compared with conventional units. For plant designers and process engineers, the new series offers a standardised yet scalable platform aimed at simplifying flowsheet design, reducing maintenance intervals and improving overall circuit performance in hard-rock and ore applications.

    Technical Brief

    • Grande Series units are configured as multi-slope vibrating screens for high-capacity classification in primary circuits.
    • Designs target heavy-duty applications in hard-rock mining, with reinforced side plates and cross-members.
    • Screen decks are engineered to accept modular media, enabling rapid change-out and tailored aperture layouts.
    • Drive systems use high-energy exciters sized for large stroke amplitudes under high material bed depths.
    • Structural layout accommodates large feed chute loads and high drop heights typical of primary crusher discharge.

    Our Take

    Metso’s Grande Series launch in Australia comes as the company is also supplying major process equipment to Harmony’s Eva copper project in Queensland, signalling that new product lines are likely to be specified quickly into greenfield designs rather than only retrofits.

    Across our mining product coverage, Metso appears repeatedly with both screening and comminution solutions, suggesting operators in Australia may increasingly favour single-vendor flowsheets to simplify integration, spares and performance guarantees.

    The cluster of December 2025 items on Metso’s screens, cooling towers and copper plant packages indicates a coordinated refresh of its offering, which could influence how Australian project teams standardise plant layouts and procurement specs over the next design cycle.

    CITIC HIC semi-mobile crusher at Duobaoshan: design and throughput notes for mine planners

    A PSZ3000-B semi-mobile gyratory crushing station, independently designed and built by CITIC Heavy Industries in Luoyang, has completed no-load and load commissioning at Zijin Mining’s Phase II expansion of the Duobaoshan copper-molybdenum mine in Heilongjiang, with all performance indicators meeting design standards. The semi-mobile unit is configured as a primary crusher station for the expanded open pit, allowing truck-fed in-pit crushing with conveyor transfer to downstream processing. For mine planners and plant engineers, the successful commissioning confirms Chinese-built large semi-mobile gyratory technology as a viable option for high-throughput greenfield and brownfield expansions.

    LEEA GLAD procurement survey: compliance and lifecycle insights for mine teams

    LEEA has launched a procurement-focused survey to feed into a new white paper scheduled for release on Global Lifting Awareness Day (GLAD) on 2 July 2026, with details hosted on the updated campaign site globalliftingawarenessday.com. Targeted at stakeholders who specify or purchase cranes, hoists, slings and other lifting accessories, the initiative centres on the theme “Not all lifting equipment is…”, aiming to capture how compliance, whole‑life cost and inspection regimes are currently weighted in buying decisions. Mining owners, EPCMs and contractors can use the findings to benchmark procurement practices against industry expectations and tightening safety standards.

    Hitachi EH5000 100,000‑hour milestone at Lumwana: capex and fleet life notes for planners

    Three 296 t class Hitachi EH5000 rigid dump trucks at Barrick’s Lumwana copper mine in Zambia have each passed 100,000 operating hours, an unusually high lifecycle for ultra-class haulage equipment in hard-rock copper operations. The milestone, marked at a joint Barrick–Hitachi recognition ceremony, points to effective component rebuild strategies, condition-based maintenance and strong dealer support for the EH5000 fleet. For mine planners and maintenance teams, it signals potential to extend truck life beyond typical replacement cycles, with implications for capex timing and fleet renewal strategies.
