Light calcium carbonate production equipment and processes

Light calcium carbonate is a kind of calcium carbonate. It is widely used in light calcium carbonate processing equipment to obtain light Calcium Carbonate Plant with a fineness of 125 mesh, 200 mesh, 225 mesh, 300 mesh, 600 mesh, 800 mesh, and 1250 mesh. Used in paper, rubber, plastic, paint, water-based coatings and other industries, with the improvement of domestic light calcium carbonate production equipment technology, the application field is also expanding, high-end cosmetics, putty powder, medicine, daily chemicals, paints, etc. The fields are differently involved, and the light calcium carbonate powder is also rising with the increase in fineness. Recently, Guangxi Province invested 100 billion yuan to promote the development of calcium carbonate industry in the province, and further promote the domestic investment in production of light calcium carbonate powder. Light calcium carbonate production process: firstly, limestone and other raw materials are burned to produce lime (the main component is calcium oxide) and carbon dioxide, and then water is digested to form lime milk (the main component is calcium hydroxide), and then carbon dioxide carbonized lime milk is introduced. The calcium carbonate precipitate is formed, and then obtained by dehydration, drying and grinding, or by metathesis reaction with sodium carbonate and calcium chloride to form a calcium carbonate precipitate, followed by dehydration, drying and milling. The milling process comprises coarsely breaking the light calcium carbonate. During the grinding stage, the fine stone material from the raw material storage is placed into a light calcium powder mill for grinding, and the ground grinding powder is sent to the super-segmentation machine. Fineness can be adjusted between 200-2000 mesh.
China is a large calcium carbonate producer with a production capacity of 15 million tons/year. The products are mainly light calcium carbonate, heavy calcium carbonate and activated calcium carbonate. Among them, nearly 500 light calcium carbonate production enterprises have a production capacity of 10 million tons per year. As the international crude oil price rises, the use of calcium carbonate as one of the inorganic fillers will become more and more extensive in the next few years. As a domestic superfine and light calcium carbonate equipment manufacturer, SBM has the MTW European version of the mill, LUM superfine Vertical mills, R-type Raymond mills and other products meet the needs of light calcium carbonate production equipment, we will also adjust the production capacity of different products according to market demand, enhance their competitiveness.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
