The Mining Mill Girth Gear is essential for optimizing the performance and efficiency of your heavy-duty grinding equipment in mining operations.
Designed for durability and precision, this robust gear facilitates the smooth rotation of mills, ensuring consistent processing of materials under high stress and extreme conditions. Ideal for both new installations and replacements, it enhances operational reliability and productivity, making it a crucial component in your mining machinery.
Product Introduction
Mining operations—from copper and gold to iron ore and rare earths—depend on large grinding mills at the heart of their concentrators. The girth gear is the critical interface between the motor drive and the mill shell, and in remote mine sites, a gear failure can take weeks to resolve if the replacement isn't readily available. Sourcing a reliable, dimensionally accurate girth gear quickly is a strategic priority for mine maintenance planners.
Hanwei delivers mining mill girth gears from Φ2 m to Φ16 m, the largest capacity available from any specialist gear manufacturer in China. Our 12 hobbing and milling machines (1–16 m) and CNC grinding fleet handle the full size range in-house, eliminating subcontractor delays.
For mining service, we emphasize three capabilities that set us apart:
First, our forged-welded construction combines the metallurgical advantages of forged tooth segments with the scalability of welded ring bodies—ideal for the 10 m+ diameter gears common in large concentrators.
Second, our reverse-engineering and on-site measurement services allow us to produce replacements for any mill, regardless of OEM, without original drawings. We've served mines across 30+ countries, often supplying gears for mills where the original manufacturer no longer provides support.
Third, our warranty terms reflect genuine confidence in product quality: up to 10 years on forged-welded girth gears, far exceeding industry norms. Whether you're planning a scheduled replacement or responding to an emergency, Hanwei's engineering team is ready to support your operation with competitive lead times and proven reliability.
