Cement Plant Cuts Energy Usage | Rockwell Automation ...
Apr 06, 2021 · While cement production expends energy at every step, the kiln is one of the most difficult to optimize. Modern cement plants typically use dry rotary kilns with calciners. The calciner preheats the raw material to about 900°C (1650°F). The calcination process is completed in the kiln, which heats the material to about 1200°C (2200°F).

How is Mercury Monitored in a Cement Kiln?
Sep 10, 2019 · Cement kilns are large furnaces used to grind and heat a mixture of raw materials (like limestone, clay, and iron ore) to produce cement. As you can imagine, that process takes a lot of energy – as can be seen by the large smokestacks that tower over the plants. As the various fuels are burned and the materials heated, air toxics are emitted.
