These fans help in effective burning of coal inside the mill. For a large clinker line there are usually 2 or 3 cement mills. Cooler exhaust fans: Cooler exhaust fans move 1.8 ton of exhaust air per 1 ton of clinker production. This process is a part of air blown into the cooler by cooling fans that are not useful for fuel combustion.

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 …

The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw meal; these reactions also involve combustion processes. The grate cooler is located downstream of the clinker rotary kiln with the purpose of suitably …
