Wet or Dry Process Cement Rotary Kiln in Cement Making Industry
Application
Rotary kiln is mainly used in three industrial fields. Firstly is
the cement making industry, secondly is the metallurgical chemical
industry, thirdly is the lime industry. For cement industry, there
are two ways to produce the cement. One is the wet process and the
other is the dry process. Our rotary kiln can be used is both
process.
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 has to be evaporated and the
process of heat transfer is not very efficient.
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.
Quite a few wet process kilns are still in operation, usually now
with higher-tech bits bolted on. However, new cement kilns are of
the 'dry process' type.
Dry process 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.
Main Features
1. Although this machine is large in form, but the structure of it
is simple. It's reliable for its using life and has less wearing
parts.
2. Hydraulic pressure gives this machine enough energy to deal with
the processing materials.
3. YCT and ZSN high efficiency motor gives the rotary kiln
reliable, energy-saving, excellent performance.
4. We also have a professional engineer team working together to
solve your specific technical problems.
