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 crusher is widely used in a variety of stone building sand (river stone, rock, sand, slag, granite, etc.), mining of metal ore, non-metallic minerals, refractory materials, glass materials, glass recycling, and it's also available as a fine crushing equipment of mineral processing equipment, it greatly reduces the pressure on the ball mill, multiple broken little mill, the mill's production is greatly increased. Limestone sand maker is mainly a kind of machine crushing the limestone into 0-5mm. Limestone goes into the sand making machine from the hopper, the material is divided into 2 parts by the feeder, one of part enter into the high-speed rotation of the impeller from the feeder, then be rapidly accelerated in the impeller, its acceleration up to several hundred times the acceleration of gravity, and then at a rate of 60-70 m/s projectile out of the three uniform impeller flow channel, projectile material is crushed by colliding with each other, and then, they impact into the vortex chamber lining together, be rebounded by the material lining, diagonal impact to the top of the whirl chamber, but also to change its direction of motion, deflected downward movement, materials emitted from the impeller to form a continuous material curtain. Limestone sand making machines are relatively common in various regions of our country, limestone crusher is the most competitive advantages and core areas of Vipeak Industry Company, however, Vipeak gravel project department has a unique advantage at Nissan 1000-40000 tons of limestone sand production line configuration, and also has more than ten years of limestone sand production line configuration experience.

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.
