Screw reactors and rotary kilns in biochar production – A …
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).

Residence time distribution and material flow studies in a rotary kiln
For example, in the rotary kiln-based direct reduction process, ilmenite and coal are employed, having a density ratio of almost a factor of 3 and widely different particle sizes. While a number of studies on rotary d r u m s [4-7] ( L I D ratios less than 10) have been reported, investigations on rotary kilns have been relatively scarce.

Mean residence time and hold-up of solids in rotary kilns
Recently, experiments have been conducted by different researchers to measure the MRT or hold-up in rotary kilns of different dimensions. However, in their experiments the hold-up at the feed end or discharge end was kept constant (Li et al., 2002, Dins et al., 2005).Consequently, the rotation speed and the feed rate had to be varied simultaneously.
