Girth gear is a main part of dryer and ball mill machining. It needs to work for very long time to have the whole barrel to rotate. So customer requirements for large ring gear is very high and strict.

Girth gear is a rotary kiln, mill main transmission parts and other equipment, mainly driven by the motor pinion drive, pinion drive mounted on the barrel of a large gear, so that the mill drive, large gear and the barrel cooperation.

Due to the girth gear modulus big, big diameter, the ring gear of our company processed using radiation plate structure, a combination of two half-ring together.
