A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous produced using rotary kilns include: Cement; Lime; Refractories; Metakaolin; Titanium dioxide; Alumina; Vermiculite; Iron ore pellets; They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
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.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
The crushed raw ingredients are made ready for the cement making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement. Generally, limestone is 80% and remaining 20% is the clay.
kiln. Inside huge rotary kilns the raw material is transformed into clinker at 1,450° C. From the kiln, the clinker goes to the clinker cooler. The cooled clinker is then transported by a pan conveyor to the clinker silo for storage. The clinker cooling can recover up to 30% of heat from the kiln .
A. A Boateng, in Rotary Kilns (Second Edition), 2016. The CementMaking Process. Rotary kilns are synonymous with cement making, being the workhorses of this industry. There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing environmental ...
P. Singh, in AbsorptionBased Postcombustion Capture of Carbon Dioxide, 2016. Preprocessing of reclaimer waste for disposal in cement kiln. A cement kiln would require uniform waste material flows in terms of quality and quantity to achieve optimum operation. Therefore, coprocessing waste in the cement industry as a substitute fuel source usually requires that the waste feed stocks are ...
