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 Mathematical modeling of heat recovery from a rotary kiln ,2010-6-1 · On the other hand exergy efficiency for rotary kiln, tras, farine and coal mill have been found 0.49, 0.13, 0.25, and 0.18 respectively. As seen in Table 2, the highest energy loss occurs in the rotary kiln process. Analysis of the waste energy potential shows that heat flows from the surface of the rotary kiln to the environment intensely.
