Recently, the demand of customers for grinding dolomite powder has increased. Many customers want to know the specific processing purpose of dolomite, and how to choose the grinding mill for grinding dolomite ore powder. The dolomite mill developed by HCMilling(Guilin Hongcheng) has rich equipment types and high quality products. We have Raymond mill, ultrafine mill, vertical roller mill and other equipment, which are all the grinding equipment that create value in dolomite powder market.


1. The 20 Application Of Dolomite

Dolomite is widely used. It can be used in metallurgy, building materials, agriculture, forestry, glass, ceramics, chemical industry and environmental protection.


1) Dolomite brick: dolomite brick is made of dolomite sand calcined from natural dolomite. It is mainly used in stainless steel refining furnace (such as AOD, VOD furnace, etc.) and cement kiln firing zone.


2) MgO Cao brick (MgO dolomite brick): MgO dolomite brick is a kind of synthetic MgO Cao refractory with large output and consumption in China. It is mainly used as lining material of stainless steel refining furnace (AOD furnace, VOD furnace, etc.).


3). Unburned magnesia calcium (carbon) brick: a refractory that can be directly used without firing, with sintered dolomite sand, magnesia and / or graphite of different particle sizes as the main raw materials.


4). Magnesia calcium system amorphous refractories: various magnesia calcium amorphous refractories, such as ramming materials at the bottom of electric furnace, coating materials for tundish, gunning materials for ladle, gunning materials for converter, gunning materials for RH furnace and self flowing hot patching materials are prepared by using dolomite.


5). Calcium aluminate cement: calcium aluminate cement (CMA) containing microcrystalline magnesia alumina spinel is a new type of binder for refractories.


6). Sintering flux: raw dolomite, limestone and quicklime are often used as flux of iron ore sintering in China's iron making industry.


7). Raw material for slag making of converter in steel works: light burnt dolomite is one of the important raw materials for slag making in the process of converter steelmaking.


8). Silicothermic magnesium smelting: Dolomite with a particle size of 30-120mm is an important raw material for the production of metal magnesium.


9). Light magnesium carbonate: light calcium carbonate is the advanced inorganic filler, reinforcing agent and good flame retardant of rubber and plastic industry, the filler of high-grade ink, pigment, toothpaste and cosmetics, and the raw material of high-grade ceramics, glass and fire retardant coating.


10). Light magnesium oxide and active magnesium oxide: the main methods to produce active magnesium oxide from dolomite are half baked dolomite and bischofite dolomite.


11). Magnesium hydroxide: in view of the shortcomings of traditional technology in the preparation of Mg (OH) 2, such as low product purity, complex process, and difficulty in industrialization, dolomite is often used as raw material.


12). Calcium carbonate: the superfine calcium carbonate with an average particle size of 5 μ m was prepared by carbonation with dolomite as raw material.


13). Magnesium containing cement: a magnesium containing cement mixed with light burnt dolomite and magnesium chloride solution or magnesium sulfate solution.


14). Building board: light burnt dolomite is used together with organic aggregate to make particleboard, sawdust board, artificial marble, thermal insulation materials and other products, which are widely used in the construction industry.


15). Interior and exterior wall coating: dolomite is properly calcined and processed into dolomite ash. It has white, strong adhesion, setting force and good fire resistance and heat insulation performance, and is suitable for internal and external wall coating.


16). Glass ingredients: dolomite is one of the main raw materials for glass production.


17). Ceramic raw materials: dolomite can not only be used as raw materials for traditional ceramic blanks and glazes, but also for preparing new structural ceramics and functional ceramics.


18). Fertilizer and soil conditioner: in agriculture, dolomite is used to make calcium magnesium phosphate fertilizer and magnesium carbonate grain loaded fertilizer. In addition, dolomite can also be used as neutralizer of acid soil, to compensate for calcium and magnesium elements, and to improve the soil.


19). Titanium dioxide alternative filler: high quality dolomite powder can be used as an alternative to expensive titanium dioxide filler.


20). Paper filler: Dolomite powder can be used as pigment filler in coating industry. It can improve the weather resistance, oil absorption and scrub resistance of the coating.


2. The Grinding Mill For Grinding Dolomite

What grinding mill can be used to grind the dolomite? HCMilling(Guilin Hongcheng) provides the special grinding equipment, which can increase capacity. Such as Raymond mill, vertical roller mill and ultrafine mill. Meanwhile, the HCH ultrafine mill can be used to grind the fine powder. It can be adjust between 325 and 2500 mesh. Furthermore, the Raymond mill can be select by different type, and they are all benefit to environment. It can be adjust between 80 and 400mesh. The vertical roller mill is the advanced equipment, which has high classify rate, large capacity, lower consumption.
