The working principles of limestone kilns are the same for rotary lime kiln and vertical lime kiln. It is well known that limestone contains mainly calcium carbonate. And when calcium carbonate is heated at proper high temperatures, usually above 1000 degrees, the decomposition of calcium carbonate will produce quicklime and carbon dioxide.
