FAQ

Q: What is the function of a SAG Mill Girth Gear?

A: The girth gear transmits torque from the pinion or drive motor to the SAG mill shell, enabling rotation and ensuring efficient grinding of ore.

Q: What material is used for manufacturing the girth gear?

A: We use high-strength alloy steel or cast steel, heat-treated to achieve surface hardness of HRC50–60, providing excellent wear resistance and load-bearing capacity.

Q: How do you ensure precise gear engagement?

A: The girth gear is machined with high precision; tooth dimensions and spacing are controlled within ±0.05 mm, reducing vibration and ensuring smooth torque transmission.

Q: What is the expected service life of the girth gear?

A: With hardened teeth and optimized structure, the girth gear's service life can be 1.5–2 times longer than untreated gears, minimizing downtime and maintenance costs.

Q: Can the girth gear be customized?

A: Yes. We can manufacture girth gears in different diameters (6–12 m), tooth counts, and segment designs to match your SAG mill specifications and operating conditions.
