Lime Kiln an overview ScienceDirect Topics

The conventional rotary lime kiln has a length-to-diameter (L/D) ratio in the 30–40 range with lengths of 75–500 ft (22.7–152.5 m) and diameter of 4–11 ft (1.2–3.3 m). Lime kilns are usually inclined at about 3°–5° slope with material charged at the elevated end and discharging at the lower end.
