How is the limestone formed by the crystal
Hypabyssal or extrusive facies volcanic rock matrix, composed of pyroxene and cryptocrystalline dark mineral glass ceramics is filled in between plagioclaseVoid formation structure.Interstitial structure.The filling material is a granular mineral.The filling material is crystalline-Glass structure.The two type of transition is called inter granular structure.
The original lime production process is the limestone and fuel (wood) layered laying, firing a week. Modern machinery, semi mechanized shaft kiln and rotary kiln, boiling furnace and other equipment for production. The calcining time is shortened correspondingly, and the production of lime in rotary kiln is only 2 to 4 hours, and the production efficiency can be increased by more than 5 times. The utility model has the advantages of a cross flow type, a double slope type, a rotary kiln for burning oil and a short rotary kiln with a preheater, etc., and the utility model has the advantages of obvious energy saving effect, and the fuel is also expanded into coal, coke, heavy oil, liquefied gas, etc..
The effective component of lime is the effective calcium oxide and Magnesium Oxide. The effective calcium oxide content in lime and Magnesium Oxide can be determined directly, can also be through the total content of calcium oxide and carbon dioxide with Magnesium Oxide's reflection, lime and undigested residue content requirements; lime powder with fineness requirements; lime powder and the volume stability, fineness and free water content requirements.The national building materials industry will be divided into three grades: building quicklime, building quicklime powder and building slaked lime powder. But in the transportation sector, JTJ034 - 2000 "highway pavement base construction technical specification" is still in accordance with the original national standard (GB1594 - 79) will be quicklime and slaked lime is divided into three grades.
An introduction to the formation of the crystalline limestone:Limestone is the name of limestone as the mineral raw material. The main component of limestone is calcium carbonate (CaCO3), which can be directly processed into stone and fired into quicklimeThe limestone is mainly formed in the shallow water environment. According to the genesis of limestone can be divided into grain limestone (water handling, sedimentary formation); biological chemical and biological chemical skeleton of limestone and limestone. The main chemical composition of limestone is calcium carbonate and easy dissolution, so in the limestone area formed the stone forest and the cave, known as Karst landform.In modern industry, limestone is the main raw material for the manufacture of cement, lime, calcium carbide, metallurgical industry is indispensable flux limestone, lime stone superfine grinding, is widely used in the manufacture of paper, rubber, paint, coatings, pharmaceuticals, cosmetics, feed, sealing, bonding and polishing products.
