Dolomite is widely distributed in nature. It is widely used in metallurgy, building materials, agriculture, forestry, glass, ceramics, chemical industry, environmental protection and other fields after being processed by crushing, dolomite grinding mill machine, etc. The following details the application fields of 200 mesh dolomite.

HC series dolomite grinding mill

(1) Environmental protection field: dolomite has the basic properties of surface adsorption, pore filtration, ion exchange between ore beds, etc. 200 mesh dolomite can be used as environmental mineral materials in the field of adsorbent, with the advantages of low cost and no secondary pollution. It can be used to adsorb heavy metals, phosphorus, boron, printing and dyeing wastewater, etc.

(2) Raw material preparation field: dolomite has a high content of CaO and MgO, the theoretical mass fraction of CaO is 30.4%, and the theoretical mass fraction of MgO is 21.7%. Therefore, dolomite becomes an important source of magnesium and calcium. Dolomite can be ground into 200 mesh fine powder as raw material for producing magnesium or calcium containing materials.

(3) Refractory field: As dolomite is calcined at 1500 ℃, magnesia becomes periclase and calcium oxide turns into crystal α－ Calcium oxide has dense structure, strong fire resistance, and the fire resistance is as high as 2300 ℃. Therefore, dolomite is often used as the raw material of refractories. The commonly used fineness of magnesia calcium brick, magnesia calcium carbon brick, magnesia calcium sand, spinel calcium aluminate refractory is 200 mesh dolomite.

(4) Ceramic field: Dolomite can be used not only in the production of traditional ceramics, as raw materials for blanks and glazes, but also in the preparation of new structural ceramics and functional ceramics. Porous ceramic balls, inorganic ceramic membranes, andalusite based ceramics are common finished products.

(5) Catalytic field: Dolomite is a good catalyst carrier, which can convert biomass with low energy density into bio oil with relatively high energy density. However, bio oil has complex components, low calorific value, strong corrosivity, high acidity and viscosity, etc. It needs to use catalyst to conduct online treatment of biomass pyrolysis steam, so as to reduce the oxygen content of bio oil and help to change the content of each component in bio oil.

(6) Sealing pressure transmission medium field: dolomite has good heat insulation and heat preservation effects. Compared with pyrophyllite or kaolinite, dolomite does not contain crystal water, which can keep the phase stable under high temperature and high pressure, and has no decomposition of carbonate substances. Therefore, dolomite is suitable as a sealed pressure transmission medium material.

(7) Other application fields: ①200 mesh dolomite powder can be prepared after sorting, crushing and grinding, and can be used as filler in paper industry after surface modification; ②The ratio of potassium feldspar to low-quality dolomite is 1 ∶ 1 to produce potassium calcium fertilizer, which is used in agriculture. ③200 mesh dolomite powder can improve the weatherability, oil absorption and scrub resistance of coatings, and can be used as pigment filler in the coating industry. ④Under high temperature environment of hot metal, magnesium vapor desulfurizer is generated in situ by reducing dolomite with ferrosilicon to desulfurize hot metal in situ. Dolomite based desulfurizer is expected to be popularized and applied in off furnace desulfurization of hot metal. ⑤The mechanical properties of light burned dolomite prepared at a certain calcination temperature mixed with Portland cement are better than those of Portland cement with only active magnesium oxide and limestone powder. The addition of 200 mesh dolomite powder has a better use. ⑥Caustic dolomite cementitious material calcined from dolomite can solve the problem of raw material shortage of magnesite in some areas. ⑦High quality dolomite is the premise of producing high quality glass. The particle size of dolomite should be within 0.15~2mm, and the iron content of dolomite should be less than 0.10%. Glass preparation is also one of the purposes; ⑧Adding 200 mesh dolomite into plastics and rubber as filler can not only improve the performance of polymers, but also reduce the cost. ⑨Reverse osmosis seawater desalination water is also one of the application fields of 200 mesh dolomite.

The above is a summary of the application fields of 200 mesh dolomite. According to the research reports in related fields, dolomite will be further studied in the fields of adsorbent, raw material preparation, refractory, ceramics, catalysts and dolomite nano. This will certainly lead to the development of 200 mesh dolomite grinding mill equipment. We are a professional manufacturer of 200 mesh dolomite grinding mill equipment.
