It notes that the rotary kiln in cement plants reaches temperatures of 1300-2200°C but this heat is usually lost to the environment. WHR technologies like organic Rankine cycle and waste heat boilers can capture up to 25% of rejected flue gases and exhaust air to generate additional energy. Industries like cement, glass, steel and …

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
