The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw meal; these reactions also involve combustion processes. The grate cooler is located downstream of the clinker rotary kiln with the purpose of suitably …
The first rotary kiln was introduced to the cement industry by Frederik Ransome (1885) when he took out a patent in England titled "Improvements in Manufacture of Cement." The first of these rotary kilns were up to 2.0 m in diameter and 25 m long, with an "enormous" production of 30 to 50 ton/day.
