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. The degree of fill is relatively deep, about 10–12%. Owing to its low thermal ...

Rotary Lime Kiln. Rotary lime kilns typically have four refractory zones. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone, where abrasion of the stone can be particularly severe. Short preheater kilns normally do not have a charging zone that sees high abrasion as preheated stone is partially softened. In the calcining zone, limestone (calcium ...
