Clinker process: kiln As the material progresses inside the kiln, the temperature increases until it reaches 1,500ºC, producing the complex chemical reactions that produce the clinker. To reach the necessary temperatures for processing the raw materials and for the production of clinker, the kiln has a main flame that burns at 2,000ºC.

Clinker Storage. Once Alite is formed at a temperature of 1450 degrees Celcius, it needs to be rapidly cooled down so that the mineral structure of clinker is retained. The hot clinker from the kiln is cooled by air in the grate cooler. Inside the cooler, there are a number of fixed and movable rows of plates with air flow nozzles.
