Clinker Cooler Tech Reduces Emissions
Posted on July 27, 2023. Despite an increased use of supplementary cementitious materials (SCMs), demand for Portland cement continues to grow. In the past decade alone, Portland cement production increased from 75 to 95 million metric tons in the United States. Clinker coolers subsequently reduce temperatures to several hundred degrees.

Temperature control: Why it is so important during clinker …
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.
