Effect of basalt on the burnability of raw meal of Portland cement clinker
This study presents the effect of basalt as a flux and mineralizer on the formation of Portland cement clinker fired at different temperatures. Five mixtures are prepared by addition of different amounts of basalt such as 0.0, 2.5, 5.0, 7.5 and 10.0 mass % to the kiln feed prepared for the ordinary Portland cement clinker manufacture.

Temperature control during clinker cooling process | VisionTIR
Clinker cooling. A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.

How Does Clinker Cooler Reduce Cement Production Energy Consumption
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 ...
