Cement Kilns: Design features of rotary kilns
The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 .

Rotary Kiln
Graeme Moir, in Advanced Concrete Technology, 2003. 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 .
