principal of kiln in cement plant

The cement kiln

Basic principle of a precalciner cement kiln. Since meal enters the kiln at about 900 C, (compared with about 20 C in the wet process), the kiln can be shorter and of smaller diameter for the same output. This reduces the capital costs of a new cement plant.
