How Does Clinker Cooler Reduce Cement Production
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 15% lower than that of other cement

Clinker: combinability of mixes Understanding Cement
If the manufacturer tries to increase the alite content too far, he may produce a clinker that has more alite, but less-reactive alite. Overall, the clinker may produce better strengths with a slightly lower proportion of more reactive alite. Effect of coal ash. Where coal is the fuel for the kiln, the raw mix composition has also to take into account the effect of coal ash, as much of the ash
CEMENT CHEMISTRY AND CLINKER MICROSCOPY The
Cement microscopy is a valuable technique for examining clinker, cement, raw materials, raw feed, and coal. Every stage of the cement manufacturing process can be improved through the use of a microscope. Most cement microscopy is done using a petrographic microscope. Usually, the specimen is a polished section of cement clinker examined using reflected light, although it may be a powder
