2.1 Types of kiln Kilns employed for burning lime may be divided into two classes[4] : intermittent kilns and continuous kilns. The latter class in turn may be sub-divided into rotary and shaft kilns. The shaft kilns may again be sub-divided into mixed feed and separate feed kilns.
The common feature of early kilns was an egg-cup shaped burning chamber, with an air inlet at the base (the "eye"), constructed of brick. Limestone was crushed (often by hand) to fairly uniform 20–60 mm (1– 2 1 ⁄ 2 in) lumps – fine stone was rejected. Successive dome-shaped layers of limestone and wood or coal were built up in the kiln on grate bars across the eye.
