    Protective coatings tougher than the elements: design notes for mine maintenance engineers

    Protective coatings tougher than the elements: design notes for mine maintenance engineers

    First reported on Australian Mining

    30 Second Briefing

    Protective wear-resistant coatings are being adopted across Australian mines and quarries to combat constant abrasion and corrosion on chutes, hoppers and crusher liners, where unprotected steel can lose millimetres of thickness in months. Products such as Loctite PC ceramic-filled epoxies and sprayable urethanes are being specified for high-slag, high-impact zones to extend service intervals on ore handling and slurry transfer assets. For maintenance engineers, the shift is towards engineered coating systems designed around specific particle size, impact velocity and chemical exposure rather than generic paint-style protection.

    Technical Brief

    • Spray-applied urethane systems are being used where flexible, elastomeric impact absorption is preferred over rigid ceramics.
    • Coatings are being selected to tolerate thermal cycling on chutes and hoppers exposed to hot, freshly crushed ore.
    • Maintenance teams are integrating coating application into shutdown windows to avoid additional unplanned stoppages.
    • Wider implication is a shift towards life-of-asset lining strategies rather than repeated plate replacement.

    Our Take

    Loctite’s positioning in Australia, as seen in both this piece and the AIMEX-focused coverage of Henkel Australia’s LOCTITE range, suggests the brand is targeting lifecycle extension of wear components as a service-cost lever rather than just a consumables line item.

    Within our 791 Mining stories, relatively few ‘Product’ and ‘Projects’ tag combinations focus on coatings, so this Loctite coverage sits in a niche area where maintenance engineering choices can materially affect shutdown intervals and project availability in Australian operations.

    For Australian sites, adopting protective coatings of the type Henkel showcases for LOCTITE at AIMEX typically becomes most attractive on assets like chutes and pumps that are hard to access, implying that early design-stage allowance for coating systems can reduce later retrofit complexity on new projects.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
