Finding failure - International Cement Review

During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance. In many instances, bearing failures at the rolls are caused by excessive dynamics in the grinding process.

Cadia Girth Gear Failures

22.09.2014· Both gears and pinions on twin ball mills failed almost simultaneously. Our 2001 paper showed that the location of the failures is explained by the shape of the girth gear blanks. Fresko et. al. [2] shows that T-gears are in fact better than Y-gears in terms of load distribution and that the diameter of the pinion in a gear set can result in excessively high loads at the ends of the pinions.

Full gear unit range for your horizontal mill | .

We often see ball mills used for clinker grinding, while vertical mills tend to be more common today for raw material comminution. In older cement plants, however, both process steps are equipped with ball mills and their corresponding drive systems. But many of these gear units have seen better days and might no longer satisfy your needs.
