  Rotary Kiln

  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
