The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.

200451 · On the other hand, concretes steam-cured at 90°C and then kept under water show significant expansion related to DEF provided that the SO3 con-tent of the portland cement is relatively high (> 4%). The higher SO3 content in the clinker phases (> 2%) or the presence of preexisting cracks accelerates the DEF-related expansion.

202156 · The substance called clinker is dark gray as the color that appears after firing while cement is produced and it is called the material that resembles the image of marble. Its production occurs as a result of heating and combining the material called limestone and clay at approximately 1500 degrees in the furnace until it becomes liquid.

202437 · Clinker is the main constituent of cement. It is essentially a mix of limestone and other minerals that have been heated in a kiln at a temperature of approximately 1450°C and transformed by heat into complex reactive minerals. Once it is produced, the clinker is finely ground and mixed with gypsum and normally with alternative constituents (raw …

2021714 · In the current research, the phase transitions in hydrated cement paste heated to a temperature in the range from 600 and 1450 °C were investigated by means of X-ray diffractometry and thermal analysis. The experimental results demonstrate that hydrated Portland cement paste can be recovered back to clinker minerals.
