The clinker cooler, also known as grate cooler or cement cooler, it is a necessary equipment of cement clinker production.The clinker cooler is mainly used to cool and transport the cement clinker. At the same time, cement cooler also provide hot-air for rotary kiln and calciner, it is the main equipment of heat recovery for burning system.. The cooler will make a sufficient heat …
It can not only grind cement clinker but also process cement admixture, such as gypsum, fly ash, furnace slag, coal gangue, etc., realizing a stable, high-quality and automated cement production. Unlike the cement production line, the …
Clinker cooling is one of the important processes in cement production. Improving the cooling effect is not only beneficial to improve the quality and grindability of clinker, reduce the power consumption of the cement mill, but also can reduce the clinker temperature, recover the waste heat, and create favorable conditions for subsequent cement handling, storage, or transportation.
The cement manufacturing process mainly includes four steps: resource extraction, raw material preparation, clinker calcination, cement grinding 17,18, and fossil fuel burning 19.
The main part of the manufacturing process of clinker takes place in the kiln. The stages in the kiln phase are as follows: Evaporation of free water: A pressure above atmospheric is required …
A: Cement is the final product obtained by grinding clinker with added gypsum, while clinker is a raw material in the cement production process. Q: Why is clinker so crucial for construction? A: Clinker provides the essential binding properties in cement, ensuring the strength and durability of concrete structures.
After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt conveyors, deep bucket conveyors, and bucket elevators).
