Specific energy consumption in cement production varies from technology to technology. The dry process uses more electrical but much less thermal energy than the wet process. ... In another study [16], it was found that cement mill, raw mill, crusher and heater consume approximately 38%, 35%, 3% and 24% of total energy, respectively. Download ...
60% of this tremendous energy has been used in the comminution units (crushers and mills) to reduce the size of raw materials and clinker 1–3 . In the mid-1990s, the vertical roller mill (VRM ...
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 …
