About the Ball Mill Girth Gear (up to 40 ft)
The Ball Mill Girth Gear (up to 40 ft) is a cast/fabricated girth ring gear, split design from the Girth gears, pinions, custom drives line, rated 500–15,000 hp mills across ratios of custom module, and most commonly found on ball mills, SAG mills, kilns. Horsburgh & Scott builds and rebuilds the biggest open gearing in America — mill girth gears, pinions, and custom heavy boxes since 1886.
When a Ball Mill Girth Gear (up to 40 ft) fails, the real decision is economic: a new unit lists at $180,000–$850,000 with a 16–30 week factory queue, a tested used unit trades at $72,000–$612,000 when you can find one, and a standard shop rebuild runs $82,800–$510,000 over 8–16 weeks. Our in-house network rate of $64,600–$418,200 in 4–10 weeks beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $4,050–$9,900, while we'll pay $8,600–$146,900 for the core as-is.
Typical failure modes on this family are bearing wear, shaft-seal leakage, and tooth-surface distress from degraded or contaminated oil. A correct rebuild means full teardown, hot-tank cleaning, magnetic-particle inspection of all gearing, verification of bearing-bore tolerances, all-new bearings, seals, shims and gaskets, reassembly to factory clearances, and a loaded run-test with warranty up to 24 months. Done right, it restores full service life at a fraction of replacement cost.
