Portland cement clinker - Understanding Cement

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

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.
