What a Girth Gear (Ring Gear) Does in Your Rotary kilns
Our custom girth gear (ring gear) castings serve as core components in rotary kilns, ball mills, rod mills — engineered to withstand high loads, continuous wear and extreme thermal or mechanical cycling while maintaining the operational stability of heavy machinery.
Because every heavy machinery project demands unique dimensions, we do not restrict your design to standard specification charts. We translate your 2D/3D engineering drawings into robust physical components with chemistry (ZG310-570, ZG35CrMo, GS-20Mn5) tailored to your wear-resistance and tensile requirements.
Common Applications & Machinery Served
- Rotary kilns
- Ball mills
- Rod mills
- Rotary dryers
