Mar 23, 2020 · Firing of cement clinker In the rotary kiln, the carbonate is further rapidly decomposed and a series of solid phase reactions occur to generate cement clinker. After a series of chemical reactions, the high temperature clinker discharged from the rotary kiln is cooled by the cement clinker cooler

cement clinker quality control during clinker production

cement clinker quality control during clinker production

In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality
