Rotary kiln Wikipedia

The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell . This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval

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
