kiln process in cement manufacturing

Wetprocess kilns. The original rotarycement kilnswere called 'wetprocess'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 wetprocess kilnmay be up to 200m long and 6m in diameter.
