4. Cement Rotary Kiln Processes Wet and Dry Cement Rotary Kiln
With the arrival of rotary kilns, 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".
(1) In the Wet Process, the kiln system is fed with liquid slurry, the water then being evaporated in the kiln.
(2) In the Semi-Wet Process, raw material is prepared as a slurry, but a substantial proportion (50-80%) of the water is mechanically removed, usually by filtration, and the resulting "filter cake" is fed to the kiln system.
(3) In the Dry Process, the kiln system is fed with dry raw meal powder.
(4) In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system.
5. Wet process cement rotary 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 has to be evaporated and the process of heat transfer is not very efficient.
The slurry may contain about 40% water. This takes a lot of energy to evaporate and various developments of the wet process were aimed at reducing the water content of the raw meal. An example of this is the 'filter press' (imagine a musical accordion 10-20 metres long and several metres across) - such adaptions were described as 'semi-wet' processes.
The wet process has survived for over a century because many raw materials are suited to blending as a slurry. Also, for many years, it was technically difficult to get dry powders to blend adequately.
6. Dry process cement rotary kilns
In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.
The dry process is much more thermally efficient than the wet process.
CITIC IC developed large new dry process cement rotary kiln product with cement research and design institutes in Tianjin, Nanjing and Hefei by using domestic advanced technology, and the product can match 3000~10000t/d large new dry process cement production line. The company has a first-rate rotary kiln development, research and design team, perfect test and inspection means and excellent large rotary kiln manufacturing equipment and manufacturing technology, and has formed a complete technology and production system integrating rotary kiln design, manufacture, install and debugging service.
