Rotary Kiln - an overview ScienceDirect Topics

Graeme Moir, in Advanced Concrete Technology, 2003. 1.3.2 The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water ...
