How Can You Decrease Mill Power In Cement Priduction 1

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

    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
