The annual cement consumption in the world is around 1.7 billion tonnes and is increasing by 1% every year [].Cement industries consume 5% of the total industrial energy utilised in the world [].A total of 40% of the total energy consumption of a cement plant is used in clinker grinding in a ball mill to produce the final cement product []. ...

Maintenance requirements for ball mills are generally higher than for a vertical cement mill, mainly due to the higher level of wear and tear on the grinding media and the liners. In contrast, vertical cement mills have lower maintenance requirements because they have fewer moving parts.

From a maintenance perspective, slipper pad / slide shoe bearings are maintenance free. It is the oil supply to them that requires the maintenance in terms of cooling and filtration. The traditional trunnion mounted mill is a well-known and widely used machine. Whereas the slide shoe supported or shell supported mill is relatively young.
