Cement Plant Cuts Energy Usage | Rockwell Automation

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).
