Introduction
Girth gears are large ring gears which are normally fitted to the outside of ball mills or rotary kilns to provide the primary rotational drive, which is required to be operated in a long time. So, the quality requirements during the actual production for the big gear ring are very high. Girth gears are applied in the mining, cement, minerals industries used in various types of horizontal mills, rotary dryers, rotary kilns and other gear ring applications in heavy processing.
