Cement Kilns: Clinker Thermochemistry

The "theoretical heat" is calculated from the clinker chemical analysis. From this one calculates the amount of each of a set of notional "compounds" that make up the clinker: this set consists of the "Bogue" phases and a further set of compounds that account for the disposition of the minor elements in the clinker.

Clinker (cement) - Wikipedia

Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary mineral handling equipment, clinker is traded internationally in large quantities.

How Cement Is Made

Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency.
