Lime Shaft Kiln

Calcium hydroxide, also known as hydrated lime or slaked lime, is a dry, colorless crystal or white powder made by treating quicklime with water, in a process called “slaking”. See photo as follows: Hydrated lime is an important product, which has variety of applications such as steel making, soil stabilization, water treatment, acid gas treatment […]

Quicklime is playing an important role in iron and steel industry, construction industry, environmental technology, and our everyday life. It is fair to say, without quicklime, there will be no modern industries and modern life. Here are typical applications of quicklime as follows: High reactive quicklime: iron and steel industry are the largest consumer of quicklime, […]

According to different burning temperature and burning time of limestone in lime shaft kiln, basically quicklime has 3 different types: high reactive quicklime, medium reactive quicklime, low reactive quicklime. We can also call it soft-burnt quicklime, medium-burnt quicklime, hard-burnt quicklime. The above scanning electron microscope images show the structure of highly reactive lime on the […]

Calcium oxide (CaO), also known as quicklime, is made by thermal decomposition of limestone which the main component is calcium carbonate (CaCO3). The process works as follows: CaCO3 + Heat → CaO + CO2  or  Limestone + Heat → Quicklime + CO2 This process is called “calcination”, main equipment to calcinate limestone is lime shaft kiln, which is the […]
