Core Components for Heavy Industry
The large girth gear (large gear ring) is a fundamental transmission component for rotary kilns, ball mills, and industrial dryers. As a vital part of the rotating mechanism, its installation precision directly determines the transmission system balance, kiln lining lifespan, and overall operational efficiency. At Tenfaye, we recognize that high-quality girth gear manufacturing is non-negotiable for minimizing unplanned downtime.

Advanced Metallurgy & Heat Treatment
Tenfaye’s rotary kiln girth gears are engineered with unique metallurgical advantages. We utilize mature, proprietary heat treatment technologies during the casting process to optimize the grain structure. This increases surface hardness and significantly enhances wear resistance and impact toughness, ensuring the gear can withstand extreme cyclic loading.

High-Strength Steel & Extended Service Life
We utilize high-strength alloy steel specifically optimized for the high-torque environments of industrial grinding mills. By tailoring the material properties to the operating characteristics of the machinery, we ensure long-term structural stability and a significantly extended service life for large-diameter gears. Efficient Mass Production & Fast Lead Times
Efficiency is at the core of our manufacturing. With a massive annual steel casting capacity, Tenfaye provides high-output mass production of girth gears. Our streamlined foundry processes ensure short casting cycles without compromising on stringent quality standards.

Precision Customization & Technical Expertise
Beyond standard sizes, we specialize in custom-made large gears. Tenfaye’s engineers collaborate with clients to manufacture components based on precise customer drawings, dimensions, and technical parameters. Every gear is a bespoke solution designed for a perfect fit.

Rigorous Quality Control & Customized Normalizing
Quality is controlled at every stage. For critical processes like normalizing medium carbon steel, we apply scientific precision to prevent surface carbon precipitation. For example, our optimized cycle involves slow heating to 810-860°C over 4 hours, a 6-hour holding period, and controlled air-cooling in a ventilated environment. This ensures the girth gear reaches its peak hardness and internal integrity.

Global Trust & Proven Reliability
Tenfaye’s industrial gear rings are the trusted choice for global leaders such as Jiangsu Pengfei Group and China Coal Group. We provide a reliable guarantee for the continuous operation of heavy-duty rotary kilns and ball mills worldwide.
