Cement Clinker Grinding Process
The cement clinker enters the tower at a temperature of 90ºC (194ºF) and within 20 seconds falls through the tower and emerges from the bottom at a temperature of 850ºC (1562ºF). From there the kiln feed enters the kiln where it is heated to 1400ºC (2552º F), resulting in the creation of clinker. After cooling, grinding, and milling the ...
