    Timken Quick-Flex coupling maintenance without moving the drive: key lessons for mine engineers

    Timken Quick-Flex coupling maintenance without moving the drive: key lessons for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    Coupling maintenance on high-torque mining drives is being simplified with Timken Quick-Flex® couplings, which allow replacement of the elastomeric element without lubrication, hub removal, or re-aligning the motor–gearbox train. The design lets fitters swap elements in situ on large drives such as conveyor head pulleys or crusher primaries, reducing downtime and avoiding the need to move heavy electric motors. Premature coupling failures are flagged as indicators of deeper drivetrain issues, prompting closer inspection of misalignment, shock loading, or bearing problems rather than simple like-for-like replacement.

    Technical Brief

    • A premature coupling failure can point to a larger problem within the drivetrain.
    • If the underlying cause is missed, replacing the component may only restart the countdown to another failure.

    Our Take

    Timken’s repeated appearance in Australian Mining product coverage, including housed bearing units and crusher life-extension pieces across 2025–2026, suggests it is positioning as a default drivetrain and bearing solution provider for fixed plant operators in Australia.

    The cluster of Australian articles linking Timken with Motion on crushers, conveyors and vibrating screens indicates that any new coupling-maintenance approach will probably be integrated into broader reliability packages for these assets rather than sold as a stand-alone component change.

    Rare Earths Americas Alpha project: leach recovery uplift and PEA notes for engineers

    Rare Earths Americas reports SGS Geosol lab tests at its Alpha ionic adsorption clay project in Bahia, Brazil have lifted rare earth leach recovery (excluding cerium) to about 40%, up from the 27% recovery assumption in Alpha’s Technical Report Summary, a 48% relative gain under different test conditions. Alpha holds an inferred 202 million tonnes at 1,520 ppm TREO at a 1,000 ppm cut-off, with NdPr and DyTb comprising roughly 21% and 3% of the basket, and 29% heavy rare earths in the tested composite. The improved metallurgical input feeds into an Initial Assessment now over 80% complete and targeted for Q1 2027.

    I-80 Gold’s Nevada growth under labour and cost pressure: key notes for mine planners

    I-80 Gold expects 2026 output at 40,000–50,000 oz as labour shortages at Granite Creek delayed access to high-grade stopes and contractor headcount sat around 100 versus a 120 target, while oxide ore from Archimedes is being stacked on the Ruby Hill leach pad, pushing some production into early 2027. The Lone Tree refractory processing restart, budgeted at about $430 million with 44% of capital committed and 20% of contingency already drawn, still targets first gold in Q4 2027 despite labour costs running 5%–10% above plan. Granite Creek’s September feasibility lifted life-of-mine all-in sustaining costs by 42% to $2,273/oz, and deeper dewatering wells plus expanded treatment capacity are now critical to the ramp-up schedule.

    Canada gold output jumps 22%: project pipeline and cost signals for mine planners

    Canada’s gold mine output surged 22% in Q3, driven by new operations such as Equinox Gold’s Valentine mine in Newfoundland and Labrador and B2Gold’s Goose mine in Nunavut, while global mine production rose only 3% to a record 1,071 tonnes. Despite this, total global supply slipped 1% to 1,369 tonnes as recycled gold fell 8% to about 314 tonnes and producer hedge books shrank for an eleventh consecutive quarter. All-in sustaining costs hit a record C$2,698/oz in Q2 and are forecast by BMO to push average all-in costs to US$2,298/oz this year, even as bullion averaged about C$4,262/oz in Q3.
