Rotary Cement Kiln Process. Kiln feed for a wet process kiln has a water content of approximately 40%. In the charging zone of a wet process kiln, steel chains are used as heat exchangers in the drying process. Chains extract heat from the kiln's hot exhaust gases to dry the slurry feed.
As the per-flow diagram of the wet process of cement manufacturing, the rotary kiln is an essential and important component of a cement manufacturing factory. 6. It is made of a thick steel cylinder of diameter anything from 3 meters to 8 meters, lined with refractory materials, mounted on roller bearings, and capable of rotating about its axis ...
In the calcination stage, the cement kiln used by the wet process is longer in comparison to the dry process, and there is no preheater and precalciner in front of the kiln. The temperature in cement kiln can reach 1400-1500℃, slurry in it is heated and dried and finally forming the clinker compounds, namely Di-calcium Silicate, Tricalcium ...
