Limestone is a non-renewable resource, with the continuous progress of science and technology and the development of nanotechnology, limestone application areas are further widened. After crushing by crusher and sand making machine,limestone can be applied in many fields.Limestone powder processing industry gradually vigorous in recent years.

Limestone can be directly processed into stone and fired into the quicklime. It includes quicklime and slaked lime. The main component of quicklime is CaO, generally blocky, pure white, containing impurities is light gray or light yellow. Lime to absorb moisture or water to become hydrated lime, lime also known as slaked lime, its main ingredient is Ca (OH) 2. After deployment,it can be made into slaked lime, lime paste, lime mortar as coating materials and tile adhesives. Cement is made from limestone and clay mixed by high temperature calcination system. Glass is made from the limestone, quartz sand, soda ash and other mixed by high temperature melting system. Smelting Iron is with limestone for flux and removing gangue. Steelmaking use lime as slag material to remove sulfur, phosphorus and other harmful impurities. Calcium carbide (main ingredient is CaC2) is made by quicklime and coke in an electric furnace reaction. Soda ash is made from limestone, salt, ammonia and other raw materials through multi-step reaction (Solvay). Caustic soda is made from soda lime and soda ash reaction (harsh method). The use of pure lime and chlorine reaction to get bleach. The use of chemical processing of limestone into important calcium salt such as calcium chloride, calcium nitrate, calcium sulfite. Lime can remove hard water being used as a water softener. Limestone burning processed into relatively pure calcium carbonate powder, used as filler of rubber, plastic, paper, toothpaste, cosmetics, etc. Soda lime is made from lime and caustic soda, as the carbon dioxide absorbent. Quicklime can be used as desiccant and disinfectants. In Agriculture, we use lime to prepare mixture of lime sulfur, Bordeaux mixture and other pesticides. Application of lime to the soil can neutralize the acidity of the soil and improve soil structure, supplying calcium the plant needed. Brush the trunk with lime to protect trees.
