Mean residence time and hold-up of solids in rotary kilns

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 .

Carbon Regeneration 911 Metallurgist

Oct 23, 2016· Consequently, the performance of the activated carbon decreases unless it is regenerated. Regeneration generally consists primarily of thermal activation in a rotary kiln at around 650 C in steam to remove organic debris. Thennal activation is preceded or followed by exposure to hydrochloric acid to remove inorganic precipitates such as carbonates.
