Lime Kiln
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.

Rotary Kiln
2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end (the fire wall). As the kiln rotates, the heated material climbs the kiln wall before flopping down and flipping over.

Modern, Efficient Pre-heater Rotary Kilns
The benefits of the pre-heater rotary kiln are in the high recovery of heat throughout the system. Heat that would typically be wasted is used to pre-heat stone and combustion air to make a highly efficient process. Other benefits include lower SOx and NOx emissions to the environment, reduced fuel consumption, and superior product quality.
