How Is Lime Made?

Calcining. Once crushed and sized, the limestone is fed into kilns where it is calcined, basically cooked, at temperatures as high as 2000 degrees fahrenheit. During this progression the extreme heat causes the limestone to chemically release carbon dioxide (co2). The end result is lime.

How Is Lime Made?

Lime is a popular building material and one of the oldest sources of construction in the world. It has been used for centuries to make mortar, plaster and other materials for buildings and structures. But how is lime made?

The process of making lime begins with the extraction of limestone from quarries. Limestone is a sedimentary rock made up primarily of calcium carbonate and other minerals. The limestone is then crushed in a crusher and transported to a lime kiln. The kiln is a large oven-like structure used to heat limestone to very high temperatures. This process is called calcination.

At temperatures of around 900-1400°C, the limestone breaks down, releasing carbon dioxide and transforming into calcium oxide or “quicklime”. This quicklime is then cooled and crushed into a powder, which is referred to as “hydrated lime”. This hydrated lime is then mixed with water to create a slaked lime or “putty” used in mortar and plaster.

The process of making lime is closely regulated to ensure the highest quality product. The temperatures and proportions of the ingredients used must be precise in order to create a good mortar or plaster. The process is also closely monitored to ensure
