Bulk material mining conveyor sprockets drive the primary and secondary conveyor systems that transport iron ore, coal, copper, gold ore, and other minerals from pit to processing plant and port. These are the largest, most heavily loaded sprockets in any industrial application.

✅ 4140 alloy steel for extreme shock loads — C45 fails in this application.
✅ HRC 45-55 hardened teeth — resists rock/mineral abrasion.
✅ Split hub / QD for field replacement — minimises expensive downtime.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
Locations: Primary overland conveyor head, secondary conveyor, stacker-reclaimer, ship-loader chain. समारोह: Convert motor torque into precise material transport motion.
ओईएम: Fenner Dunlop*, Continental*, Rema Tip Top*, Metso* systems. *Compatibility reference only.
चुनना: ❶ Match chain pitch ❷ Shaft bore → hub type ❸ Tooth count for speed ratio ❹ Material grade for environment ❺ Surface treatment for corrosion protection.
Install: LOTO → release chain → remove old sprocket → mount new (split hub = no chain removal) → align → tension 2-3% → lubricate → test.
Issues: Chain riding teeth = worn sprocket (replace both). Vibration = misalignment/bore runout. Excessive noise = dry chain. Chain skipping = elongated chain + worn teeth (replace both).
Pilbara, WA: “4140 sprockets on our primary drive. Extreme conditions, excellent performance.” ★★★★★
Newman, WA: “Split hub saved hours during shutdown. Material certs provided.” ★★★★★
Mackay, QLD: “Consistent quality across multiple orders. Hardened teeth lasting well.” ★★★★☆
Perth, WA: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Gladstone, QLD: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
