Modelling and optimization of a rotary kiln direct ...

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 ...

Burning : In this operation, the slurry is directly fed into a long inclined steel cylinder called Rotary kiln.Inthis kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart (i) Drying Zones : In the wet process, the drying zone is comparatively larger than dry process. In is because the raw material in slurry form is directly fed into the kiln which has ...

Rotary Kilns - KHD International

Rotary lime recovery kilns typically have four refractory zones (figure 1). These wet process kilns use chain systems in the charging area to dry the slurry feed. In the preheating zone, the mud feed is heated in preparation for the burning zone, and refractories range from fireclay (40% Al2O3) brick up to 70% alumina brick
