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. It has to be long because a lot of water ...

The knowledge of wet process kilns design and operation in the cement industry has not been improved substantially during the last decades since the pre-calcination process has been developed to become the technological standard. In spite of the tendency to replace wet process rotary kilns for cement production by modern dry process kilns with pre-calcination, there are still a substantial ...

There are two different processes for manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder-like substance. Both the processes are in use and have their own advantages and disadvantages.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

With the arrival of rotary kilns in Britain in 1900, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal".

In contrast to static kilns, the material passes through quickly: it takes from 3 hours (in some old wet process kilns) to as little as 10 minutes (in short precalciner kilns). Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance.
