Rotary Kiln Process. The material is entered into one side of the kiln and as the rotation occurs, the material slides down through the tube and goes through a certain amount of mixing and stirring. Hot gasses pass through the kiln, and these gases either come from an external furnace or may be generated inside the kiln.

Barring the continuance of some old wet-process or semi dry process kilns in different countries, the new and modern plants almost exclusively operate dry-process 5-stage preheater–precalciner kiln systems with efficient grate coolers. Such kiln systems are also provided with multichannel burners having high flame momentum.

In a wet-process or preheater system without a pre-calciner, most of the calcination takes place in the rotary kiln within a moving mass of feed. This situation is not ideal for calcination because heat transfer has to take place through a large mass of material and CO 2 has to escape outwards as heat moves inwards.

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated ...
