Temperature control during clinker cooling process | …

A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.
