good performance dry process cement rotary kiln Description

The cement kiln

Wet process kilns. 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.

In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system. In addition to these distinctions, a further category has emerged in the last 40 years: Precalciner Kilns, in which a proportion of the kiln fuel is burned in a static preheater before the feed enters the rotary kiln.
