Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.Advanced process control for the cement industry,Controlling a cement kiln has always been a challenging task for cement plant operators. These days, a computer-based pyro control system is not merely nice to have, it is a practical necessity.

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,PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL,A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC atwhich temperature is optimum for clinker grinding,which temperature is optimum for clinker grinding.
