Dolomite ore is widely used. The dolomite mill developed by Hongcheng Mine has a wide range of equipment types and high-quality products, including Raymond mill, ultra-fine pulverizer, vertical mill and other equipment. It is the grinding equipment that creates value in the dolomite ore powder market.
1. Detailed introduction of 20 dolomite uses
Dolomite can be used in a wide range of fields and can be used in metallurgy, building materials, agriculture, forestry, glass, ceramics, chemical industry and environmental protection. See below for detailed explanation.
(1). Dolomite bricks: Dolomite bricks are made of dolomite sand calcined from natural dolomite, and are mainly used in stainless steel refining furnaces (such as AOD, VOD furnaces, etc.) and in the firing zone of cement kilns.
(2). Magnesia calcium brick (magnesium dolomite brick): magnesia dolomite brick) is a synthetic magnesia-calcium refractory product with a large output and consumption in my country, and is mainly used as a lining material for stainless steel refining furnaces (AOD furnaces, VOD furnaces, etc.).
(3). Unburned magnesia-calcium (carbon) brick: a refractory material that can be used directly without firing, using sintered dolomite sand, magnesia and/or graphite of different particle sizes as the main raw materials.
(4). Magnesium-calcium-based amorphous refractories: Dolomite is also used to prepare various magnesium-calcium amorphous refractories, such as electric furnace bottom ramming material, tundish coating material, ladle gunning material, converter gunning material, RH furnace spraying material Unshaped refractory materials such as replenishment, self-flow heat replenishment, etc.
(5). Calcium aluminate cement: Calcium aluminate cement (CMA) containing microcrystalline magnesium aluminum spinel is a new type of binder for refractory materials.
(6). Sintering flux: my country's ironmaking industry often uses raw dolomite, limestone, quicklime, etc. as the flux for iron ore sintering.
(7). Slag-making raw materials for converters in steel mills: light-fired dolomite is one of the important slag-making raw materials in the production process of converter steelmaking.
(8). Silicon thermal magnesium smelting: Dolomite with a raw material particle size of 30-120mm is an important raw material for the production of metal magnesium.
(9). Light magnesium carbonate: Light calcium carbonate is a high-grade inorganic filler, reinforcing agent and good flame retardant in the rubber and plastics industry, a filler for high-grade inks, pigments, toothpaste and cosmetics, and a filler for high-grade ceramics, glass and fireproof coatings. raw material.
(10). Light magnesium oxide and active magnesium oxide: There are mainly semi-roasted dolomite method and bischofite dolomite method to prepare active magnesium oxide from dolomite.
(11). Magnesium Hydroxide: In view of the shortcomings of low product purity, complex process, and difficulty in industrialization in the preparation of Mg(OH)2 by traditional processes, Chang Jiang et al. used dolomite as raw material.
(12). Calcium carbonate: Cao Ling and others used dolomite as raw material to prepare ultrafine calcium carbonate with an average particle size of 5 μm by carbonization.
(13). Magnesium-containing cement: Magnesium-containing cement prepared by mixing lightly burned dolomite ore with magnesium chloride solution or magnesium sulfate solution.
(14). Building board: Lightly burned dolomite mixed with organic aggregates can be used to manufacture particleboard, wood chipboard, artificial marble, thermal insulation materials and other products, and is widely used in the construction industry.
(15). Interior and exterior wall coatings: Dolomite is properly calcined and processed into dolomite ash. It has whiteness, strong cohesion, coagulation and good fire resistance and heat insulation properties, and is suitable for interior and exterior wall coatings.
(16). Glass ingredients: Dolomite is one of the main raw materials for the production of glass.
(17). Ceramic raw materials: Dolomite can not only be used as the raw material of traditional ceramic blanks and glazes, but also can be used to prepare new structural ceramics and functional ceramics.
(18). Fertilizers and soil conditioners: Dolomite is used in agriculture to manufacture calcium magnesium phosphate fertilizers and magnesium carbonate granular fertilizers. In addition, dolomite can also be used as a neutralizer for acidic soils, compensating for calcium and magnesium elements, and improving the soil.
(19). Titanium dioxide substitute filler: high-quality dolomite powder can be used as a substitute for expensive titanium dioxide filler.
(20). Papermaking filler: Dolomite powder can be used as a pigment filler in the coating industry to improve the weather resistance, oil absorption and scrub resistance of coatings.
2. Dolomite mill for grinding
What mills can be used to grind dolomite powder? Raymond mills, vertical mills, ultra-fine mills and other equipment provided by Hongcheng Mining are all mills that increase production capacity. Among them, HCH ultra-fine ring roller mill can be used for grinding fine powder, and the fineness of the grinding can be between 325-2500 mesh; and there are many types of Raymond mills that can be selected, and these mills are energy-saving. The environmental protection special grinding equipment can grind the fineness between 80-400 mesh; the vertical grinding equipment is an advanced equipment for improving production and efficiency, with high classification efficiency, large production capacity and lower energy consumption.
