the core of the entire cement producing process: the clinker formation the rotary kiln. in Thus, in order to maintain or even improve clinker quality (and ), we need a better understanding of output the development of clinker properties inside the kiln …
Details
To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature and alkali attack. Typically kiln feed used to make cement clinker enters the cooler at 1400°C and cools to about 150°C as it travels to the outlet.

In cement production, the clinker burning process with the cyclone preheater, the kiln and the clinker cooler, is the heart of the process. The design and the process technology selected along with the relevant process automation have an important influence in cement quality. The speed of cooling influences the clinker properties considerably:

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 …
Details 
The thermal efficiency of a cement cooler refers to the percentage of the total heat recovered from the high-temperature clinker and the physical heat of the clinker. The higher the thermal efficiency, the more heat is recovered, which can be used to preheat the combustion air in cement kiln, saving energy and fuel cost.

Rotary cooler is also called clinker cooler, which is the important support equipment of cement rotary kiln. It is mainly used to cool the high-temperature clinker（1000-1200℃）discharged from the rotary kiln into an appropriate temperature (less than 200℃). The cold air produced by it contact countercurrent with the clinker in the ...

A clinker cooler is a major element of manufacturing clinker. Cement turns into clinker when it dries after moving through a rotary kiln. The raw materials (clay, limestone, and some minor additives) are ground and blended in a raw mill. At this point, the mixture is called kiln feed. When cement clinker leaves the kiln, it is very hot.

The Clinker Cooler operates at 260 to 325 strokes per minute – stroke varies from 0.6 to 1. inches. Manual speed control makes it possible to maintain proper cooling conditions under varying loads. The smooth conveying motion results in a continuous agitation and turning of the clinker bed without excessive degradation.
