Girth gear is an important transmission part of rotary kiln and ball mill equipment. The motor drives the pinion and pinion drives the girth gear mounted on the cylinder shell, because of this, the ball mill start driving. The girth gear is connected to the cylinder shell by bolt.

THE LIFE LINE OF THE MILL. Regular maintenance of the Girth gear is an area of the mill's drive train that can be neglected by a maintenance department, albeit quite unintentionally. This oversight can result in failure or excessive wear, or both, which causes unplanned, costly mill down time.

Gears exhibiting worn or missing teeth or damaged gear mounting should be replaced as soon as possible. This can be observed by examining the gear mesh – the way in which the girth gear and pinion gear come together at the point of joining.

Jul 16, 2003· I've worked with girth gear problems in many plants, on various rotary kilns ball mills (up to 5000 hp). The previous responders are spot on regarding the cause of pitting. There are some additional methods for correcting pitting on the girth gear regarding carburized pinions and machine in place technology.

Jul 16, 2003· There are some additional methods for correcting pitting on the girth gear regarding carburized pinions and machine in place technology. Had good luck with that procedure on a 4000 hp ball mill over 4 years ago, which saved a 600,000 girth gear reverse, and also saved the back side of the girth gear for the future reverse.
