Calcination is the process of heating a solid material in order to cause chemical separation of its components. The diversity of chemical separation lends calcination to accomplishing a range of objectives, from the removal of chemically bound (crystalline) water, to the volatilization of contaminants from a source material, thermal decomposition, and even …

ABSTRACT. Lime is a product derived from the thermal decomposition of limestone (mainly calcium carbonate, CaCO 3) into quicklime (CaO) and carbon dioxide (CO 2), also called calcination.Controlled reaction with water is used to manufacture hydrated lime (Ca(OH) 2) products.Lime is used in a wide variety of applications: metals industry, …

Over Burn for Large Size Limestone. The selection of limestone particle size has a great impact on lime calcination. Due to the porous and poor heat transfer properties of the naturally generated limestone layer, when the temperature reaches 1250-1350℃, the surface of the limestone will be overburned, shrink and crack, making it impossible to …
