Ball mills are rotary equipment with relatively high speed of operation commonly used at industry. In fact, due to this higher speed of rotation all the components: pinions, gears, main and auxiliary drives has to be set in a very precise way. Mutual, correct positioning of such elements guarantees their durable and longterm operation.

A common failure cause of gear driven mill systems is misalignment, which in its most severe form can cause rapid tooth fatigue and fracture. The operating temperature profile of girth gear pinions give an indication of the pinion's overall alignment with the girth gear. High differential temperatures from end to end indicate misalignment.
