Cement Kilns: Clinker

Although the other potential ingredients may be cheap natural materials, clinker is made in an energy-intensive chemical process - in a kiln - and its production is the main concern of this website. Between one and two billion tonnes a year of clinker are made world-wide, and the details of its formation are therefore of great economic significance, since no viable alternative …

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.
