Precision casting, German standards and full manufacturing process can be under control.
 
Large girth gear processing capability

1. Diameter can up to 15m, which processing capability could cover 90% demand for ball mill and rotary kiln girth gears in global.
2. Width can up to 2m that could meet the heavy duty load conditions, no matter in cement or mining industry.
3. Strictly implement DIN 3962, Class 7 is better than the industry’s conventional Class 10.
4. Spur girth gear/helical girth gear and double helical processes.
5. Segmented and integral girth gear help customer to solve transportation/installation problems. 

Teeth Grinding

1. Achieve DIN 3967, Class 4.
2. With the diameter from 1000mm to 7000mm.

Girth Gear process advantages from Tenfaye

1. CNC forming teeth grinding can help eliminate heat treatment deformation.
2. Adaptive shaping technology can compensate for the installation deviations and extend the service life by 30%.

Material for girth gear from Tenfaye is using the DIN EN 1563 certified cast steel (ZG42CrMo/ZG34CrNiMo), which has mechanical properties and can reduce wear rate by 35%. The most important is the world’s top 10 groups in mining industry always require DIN EN 1563 materials for girth gear and ring gears.
 
Tenfaye has been already provided girth gear solutions for mining/cement/metallurgical in more than 32 countries with competitive price and good service.
