How Does Clinker Cooler Reduce Cement Production Energy

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

Rotary Cooler: rotary cooler is the earliest used one in the cement plant.It is similar to the cement rotary kiln in appearance and equipped with refractory lining and material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange.

Clinker cooler level and pressure measurement VEGA

To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air.

Cement Cooler Clinker Cooler Types Of Clinker Cooler

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.

These changes also affect the core of the entire cement producing process: the clinker formation in the rotary kiln.

Effects of grate cooler dynamics on cement process

2020-10-13  The cement clinker leaving the kiln consists of hard granular particles ranging from 1/8 inch to several inches in diameter. This clinker is transported through a cooler (Figure 1) on a moving grate while a controlled stream of air passes through the bed of clinker. The heated air from the cooler is then used for burning the fuel in the kiln.
