The rate of clinker cooling, from maximum temperature (1450 °C) till the melt stiffening, has also high influence on clinker phase composition and thus on its properties.
Upon exiting the kiln, the cement clinker is cooled to approximately 80ºC. Gypsum is then added to the composition and the cement clinker is ground down into cement powder, ready for storage, packaging and transport. How is cement cooled? Cement cooling is an important step in the cement production process, as it reduces …
A grate clinker system is used in cement production and clinker burning system consists of a clinker cooler, the rotary kiln, and the suspension pre-heater [6].A clinker cooler reduce the temperature of the clinker, and grind and recover energy from the sensible heat of the hot clinker by heating the cooled air.
