Limestone

Limestone, also known as calcium carbonate, a kind of compound, whose chemical formula is CaCO3, CAS number 34-471-1. It is a common substance on earth, which can be found in the rocks. It is the main component of animal back shell and snail shells, exists in nature by calcite and aragonite the two kinds of minerals. Calcite belongs to trigonal system, it’s the hexagonal crystal, and pure calcite is colorless, it’s white in usual. It’s containing 56% CaO, 44% CO2, the density is 2.715g / cm³, the Mohs’ scale of hardness is 3, it’s brittle. Aragonite belongs to orthorhombic strain, it’s the diamond crystal, and the color is gray or white, the density is 2.94g/cm³, the scale of Mohs’ hardness is 3.5 to 4. In the physical properties of limestone, calcite crystal size is very important. It has a high strength for dense limestone to show the fine crystal structure of low porosity. The density of limestone is 2.65~2.80g/cm³, dolomite limestone is 2.70-2.90g/cm³, and dolomite is 2.85-2.95g/cm³. The bulk density depends on the porosity.

Technological Process

Limestone crushing production line is an important production processes in burnt lime production line and cement production line. Cement can be crushing by Vipeak limestone crushing plant into coarse and fine powder, so as to achieve the national use standards and customer requirements. It is easy to use, particle size of the crushed product is relatively uniform, long service life, low noise, low dust, easy to maintain and repair, low vibration.The specific work flow: Materials transported by vibrating feeder to Jaw crusher, then carried by a conveyor into the back-crushing Cone crusher for fine crushing, and then the material go into the vibrating screen for screening, after crushing, finished materials is sent out by the conveyor, substandard materials are transported back to Impact crusher or Cone crusher for crushing again. With the foreign high-grade calcium carbonate material entering the Chinese market, promote domestic technological progress, accelerate the rapid growth of China's deep-processing varieties of calcium carbonate, and towards the rapid development of diversification, professionalization, and refine direction to expand more applications. Vipeak Group has been successfully installed a full crusher production line for many limestone production line domestic investors, and provide a guarantee for customers to obtain economic benefits, which is the best choice for crusher equipment buyers.

Application Fields

Limestone can be widely used as building materials, which is an important raw material in many industries. Limestone can be directly processed into stone and fired into the quicklime. Lime includes quick lime and slaked lime. The main ingredient of quicklime is CaO, usually in blocks, white when it is pure, pale gray or pale yellow when impurities. Lime becomes hydrated lime after absorbing moisture or adding water, hydrated lime also called slaked lime, its main ingredient is Ca (OH)2. Slaked lime is formulated into a stone mortar, lime paste, lime mortar, which is used as coating materials and tile adhesives. Cement is a mixture of limestone and clay, prepared by high-temperature calcinations. Glass is making of the mixing limestone, quartz sand, and soda ash which are melting in high temperature. Iron making is using limestone for flux to remove the gangue. Steel making uses quick lime as the slag making materials to remove sulfur, phosphorus and other harmful impurities. Calcium carbide (main ingredient is CaC2) is obtained by quick lime and coke reaction in an electric furnace. Soda ash is obtained by reaction of limestone, salt, ammonia and other raw materials through multi-step (solvay process). Making caustic soda by reaction of slaked lime and sodium carbonate. To prepared bleaching by using the reaction of pure lime and chlorine. We using the limestone chemical processing to make calcium chloride, calcium nitrate, calcium sulfite and other important calcium. Lime can temporarily remove the hardness of water, so it is used as a hard water softener. Limestone burning processed into relatively pure calcium carbonate powder, can be used as filler of rubber, plastics, paper, toothpaste and cosmetics. The soda lime is made of lime and caustic soda, also be used as the carbon dioxide absorbent. Quicklime used as a drying agent and disinfectant. Agriculture, quick lime is used to make mixture of lime sulfur, Bordeaux mixture and other pesticides. Application of hydrated lime to the soil can neutralize the acidity of the soil, improve soil structure, and supply the necessary calcium for the plant. Brushing the trunk with lime slurry can protect trees.
