Introduction of Limestone
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are a large amount of raw materials used in construction materials and industry. Limestone can be directly processed into stone and burned into quicklime. Quicklime CaO becomes slaked lime by absorbing moisture or adding water. The main component of slaked lime is Ca (OH) 2, which can be called calcium hydroxide. Slaked lime is formulated into lime slurry, lime paste, etc., used as coating material and tile adhesive .
It is widely used in varied industries for environmental protection and use in industrial processes and applications, in the non-ferrous metals and minerals, iron and steel, chemicals, portable water, pulp and paper, oil & gas, cement and construction, agriculture, animal husbandry and aquaculture. Other applications are in waste water and sludge treatment, sugar refining, flue gas treatment, glass and ceramics, roads and soil stabilization, food preparation, supplements and many more.
Application of Limestone powder
Limestone for Highway Asphalt Industry
Limestone ore powder plays a filling role in the asphalt mixture, the purpose is to reduce the gap of asphalt concrete, reduce the amount of cement, improve the work ability of concrete, and reduce the heat of hydration.Asphalt mixing plants generally use limestone powder of about 180-200 mesh to improve the adhesion between asphalt and aggregate.
Limestone for Desulfurization Industry
Limestone desulfurization utilizes lime or limestone slurry to absorb sulfur dioxide in the flue gas in the absorption tower to obtain a mixed liquid of calcium sulfite and calcium sulfate, and then sends it to the oxidation tower, where it is oxidized by air, and the resulting calcium sulfate slurry is centrifugally filtered And after washing to make finished calcium sulfate
Limestone used for Soil improvement Industry
Quicklime is used as a desiccant and disinfectant. In agriculture, quicklime is used to prepare lime sulfur mixture, Bordeaux mixture and other pesticides. The application of hydrated lime in the soil can neutralize the acidity of the soil, improve the structure of the soil, and supply the calcium required by the plants
