The excess hot air from the Cooler is Sent to the precalciner via the Hot air duct. The settling chamber returns the dust to the Deep Bucket Conveyor mounted below the cooler. The light particles in the cooler is carried to the Electrostatic precipitator & dust particles are returned to the DBC via Enmass conveyors.

The modern cooler. Clinker cooling is a key step in the pyroprocessing system. The cooler is essential for recuperating heat from the clinker and cooling it sufficiently for the cement milling operation. However, the primary objective of the cooler is to transport hot clinker from the kiln. During this process, the cooler fulfills a range of ...

The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be …

Clinker leaves the cement kiln usually at more than 1200℃ and it carries a heat content of about 1250-1650 kJ/kg. So it needs to be cooled to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Even if some of them have crystallized, they are ...
