In case study 2, following the change of the bearings of the grinding rolls, the plant team was looking for a way to reduce the risk of bearing failure. 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.

Cement plants form a challenging environment for rotating equipment. Significant amounts of silica dust occur as a by-product of certain construction processes. Over time this dust subjects rotating equipment, including Raw Mill fans, to high levels of erosion which ultimately reduces the plant's output over time.

Reliability, availability and maintainability analysis of ...

At Tarmac (Dunbar, UK), their existing Raw Mill fan was replaced with an enhanced Howden design in 2007. This Howden fan was specifically designed to handle the high silica dust burden that Tarmac face in their Dunbar plant. Over the past 12 years it has been performing to the highest of standards with only minimal outage repairs. Read case study
