CHAENG can offer high-quality girth gears for ball mills, rotary dryers, and rotary kilns according to users' drawings and requirements. The girth gear drives the entire tube body to run for a long time. Therefore, in actual production, the quality requirement of the girth gear is high.
Our company has advanced casting, machining, and testing equipment, and sets up a strict quality management system to control every step of the manufacturing process and ensure the high quality of girth gears.

1. Use CAE software to simulate the filling and solidification process of castings, so as to optimize the process.
2. Professional heat treatment process to improve the hardness, wear resistance and impact resistance of the girth gear.
3. Advanced machining equipment and technology to ensure the dimensional accuracy.
4. Sandblasting and shot blasting equipment effectively improves surface quality.
5. A scientific production management system to ensure the product quality and delivery time required by customers.
6. Complete inspection system to ensure quality: chemical composition, mechanical property, dimensional check, ultrasonic testing (UT), magnetic particle testing (MT), penetrant test (PT), etc.
