Aug 01, 2006 For rotary kilns without a discharge dam, an equation was fist given by Sullivan et al. (1927) to calculate the mean residence time of the solids: (1) MRT = 1.77 L D Θ n β. Accordingly, MRT is proportional to Θ and the size ratio L / D, but inversely proportional to the rotation speed n and the kiln inclination β

Dec 26, 2019 The charge material moves from the feed end to the discharge end as a result of the rotary motion and gravity. The inclination of the kiln is between 1.5 % and 5 % and varies only in experimental kilns. Speed of the kiln ranges between 0.2 revolutions per minute (rpm) and 2 rpm. Normally variable-speed drives are used to control the residence time
rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln
conversion kilns, which comprise a hydrolysis reactor and a rotary kiln fitted with lifters. Rotary conversion kilns are externally heated by resistors located close to the outside wall of the rotating cylinder. Various studies have been carried out on conversion kilns in an attempt to simulate their hydrodynamic, chemical and thermal behavior [5]
