Girth gears are used in a number of the world’s critical industries, including mining, cement and minerals. Usually fitted to the outside of horizontal mill, ball mill and rotary kiln.
Girth gears provide the system’s primary rotational drive and need to be robust, efficient and built to last. They are used in mining, cement and minerals processing, including copper, gold, silver, platinum and iron ore production, where operational downtime is not an option.
