Manufacturing - the cement kiln - Understanding Cement

In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln. The dry process is much more thermally efficient than the wet process.

Cement Manufacturing: Fine Construction Materials From the Grinding Rolls

The basic principle of cement manufacturing has been the same for decades: Mills crush the raw material mixture into a fine rawmix, which is simultaneously dried by injecting dry air. The heat source is waste heat from the rotary kiln in which the powder is neutralized (losing CO2) and sintered to become clinker.
