fed to the kiln, the kiln design, the presence of preheaters, recuperators and coolers, the type and thickness of re- fractories used to line the kiln, and the scale of operation. For rotary kilns fed with dry stone, reported energy requirements 4 are in the range 6 to 8 GJ/tonne CaO, which
— A rotary kiln is a unique facility with widespread applications not only in the process industry, such as building-material production, but also in the energy sector. There is a lack of a more comprehensive …
The rotary kiln is used in many solid processes, including drying, incineration, heating, cooling, humidification, calcination and reduction. This widespread application can be attributed to factors such as the ability to handle varied loads, with large variations in particle size [1]. The rotary kiln is a slightly inclined steel cylinder that ...
— Rotary kilns can either be used in continuous or batch mode [56], [57]. While batch rotary kilns offer some benefits over continuous rotary kiln as easier operation and simpler construction, they will not be the focus of this paper, as they seem to only play a minor role in research (See Chapter 3.1 and Table 9).
— A number of samples from the pre-burning zone of a wet-process cement rotary kiln were examined by combined DTA/TG and XRD for estimation of spurrite (2Ca2SiO4·CaCO3).
