FEECO recommends replacing both the girth and pinion gears at the same time to avoid the risk of damaging a new gear by pairing it with an old, worn-out gear. Additionally, because the gear is part of the drum's structure and mechanical stability, once the gear has been replaced, a full laser alignment will be needed to realign the drum.

The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or a girth gear unit with pinion design (central gear unit: helical gear unit).
This gear unit type was developed for driving tube mills with girth gears. Here, the gear unit forms a single unit with the girth gear with which it meshes directly. Compared to the traditional pinion/girth gear variant with external pinion and girth gear, the system with the gear unit for the girth gear is by far more favorable.
