How Lime is Made

Calcining – the kiln fuel is burned in the preheated air from the cooling zone and, as the limestone moves down the kiln, the heat turns the limestone into quicklime and carbon dioxide (CO 2). Cooling – quicklime leaving the calcining zone is cooled by direct contact with "cooling air."
