How is lime produced?

The original lime production process is to lay limestone and fuel (wood) in layers and calcine them for one week.

In modern times, mechanized and semi-mechanized vertical kiln, rotary kiln, boiling furnace and other equipment are used for production. The method is to first heat calcium carbonate to 1 100 degrees Celsius, and calcium carbonate will be decomposed into calcium oxide and carbon dioxide. When carbon dioxide is discharged, lime can be made.

Because the raw material of lime is very common and the production cost is low, lime powder is often used as a desiccant and placed in the packaging of food (mainly snacks). When the ancient Romans were building, they would mix lime and volcanic ash into building materials, which is the earliest cement in history.

Lime and limestone are widely used as building materials and important raw materials for many industries. Limestone can be directly processed into stone and burned into quicklime. Slaked lime is mixed into lime slurry, lime paste, lime mortar, etc. , used as coating and tile adhesive.
