Advanced Process Control for Clinker Rotary Kiln and Grate Cooler
2023年3月3日 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 cooling the clinker.

EVERYTHING YOU NEED TO KNOW ABOUT OPERATION AND
It is extremely important for the operator to master cooler controls as well as other control functions of the rotary kiln system, because the cooler itself performs an integral part of the clinker-burning process. Cooler conditions influence the burning process in the kiln and consequently, the quality of the clinker.
