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".
Wet process cement rotary kilns Wet and Dry Cement Rotary Kiln 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. Dry process cement rotary kilns Wet and Dry Cement Rotary Kiln 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. Company Information
