Ring gear

We 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.

through 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.

Specification:
