As the largest rotating equipment structures in the world, rotary kilns operate with perhaps the biggest challenges. Cement clinker and iron ore pellets produced by kilns are critical to production. Yet kiln maintenance is usually time based, so hard driven components must last until the next interval.
Rotary kilns (Figure 1) are used for a range of mineral processing operations. Kilns range in size from 26 m in diameter and can be 50225 m long with an operating mass of up to 3000 t.
