22 Module Custom Made Girth Gears For Horizontal Mills
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 mills, rotary mills and kilns, girth gears provide the system’s primary
rotational drive and as such need to be robust, efficient and built to last.
Girth gears are used in a number of mining, cement and minerals processing applications, including copper,
gold, silver, platinum and iron ore production where operational downtime is not an option.
