Kilns

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. That's not so easy when even the kiln's outer shell can reach 400 °C - enough to reduce lubricant viscosity inside bearings and eventually cause failures.
