The price of heavy calcium carbonate powder of 400 mesh varies, depending on different regions, different production costs and different whiteness. Heavy calcium with 400 mesh is usually used as filler, and it is widely used in industries of rubber, plastics, paper-making, coatings, building material, food, medicine and feed.
Application of heavy calcium in various industries:
1. Coal-fired power plant industry
The main use of calcium carbonate in coal-fired power plant industry is flue gas desulfurization. limestone flue gas desulfurization refers to synthesize calcium sulfite from calcium carbonate and sulfur dioxide produced during coal combustion, and then calcium sulfite can oxidize into gypsum when in contact with air, the gypsum can effectively reduce the emission of sulfur dioxide by 90%. At the same time, the produced desulfurized gypsum can be sold directly to cement plants or gypsum board plants as products.
2. Paint industry
The use of heavy calcium in paint is mainly to reduce costs and increase hardness. Generally, when it is used as the main filler, the particle fineness is required to be around 400 to 325 mesh, and the whiteness is not less than 80%.
3. Feed industry
Heavy calcium used in feed industry requires fineness 325 mesh, whiteness 95%, purity 99%, without impurities. Calcium carbonate can increase the calcium content in the feed and improve the quality of the feed.
4. Floor tile industry
For floor tiles, the requirement for heavy calcium is: 400 mesh, whiteness 95%, purity: 98.5%, without impurities. When used in floor tile, calcium carbonate can increase the whiteness and tensile strength and improve the toughness of the product, meanwhile reduce production costs.
5. Paper-making industry
Heavy calcium carbonate for paper-making requires fineness over 325 mesh, whiteness 95%, purity 98%. Calcium carbonate plays an important role in paper-making industry. It can ensure the strength and whiteness of paper, and reduce cost.
6. Rubber industry
When heavy calcium used in rubber, the fineness needs to reach 400 mesh, whiteness 93%, purity 96%. Calcium carbonate is one of the mostly commonly used fillers in rubber industry. It can increase the volume of rubber products and save natural rubber to reduce cost. With calcium carbonate as filler, rubber can obtain higher tensile strength, tear strength and wear resistance than pure rubber vulcanizate.
7. Artificial marble industry
When filled in artificial marble, fineness of heavy calcium needs to be around 325 to 400 mesh, whiteness 95%, and purity 98.5%, without impurities. At present, calcium carbonate is widely used in the production of artificial marble.
Application prospect
With the continuous expansion of market demand, the application prospects of heavy calcium will be broader. In a word, heavy calcium would have great economic value and market potential in future.
In order to meet different requirements in different application fields, to classify heavy calcium with different fineness is indispensable, so the use of grinding and classifying equipment is indispensable for better application of calcium carbonate, eg: ball mill and classifier.
