Dry-process Kiln

Compared with the wet-process rotary kiln, the dry-process makes the raw meal into the raw drymeal which has less than 1% moisture content. So it saves the heat needed in evaporation of water in the wet-process. The hollow type kiln has a lager amount of heat consumption due to its high temperature of waste gas.

The dry-process makes the raw material into drymeal whose fluidness is worse than slurry and can not be mixed well.
