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).
