Application of Dolomite

China is rich in China is rich in dolomite resources, and the proven reserves can meet the needs of economic construction. Many mineral deposits have been developed and utilized, with production areas spread throughout various provinces. At present, dolomite is widely used in metallurgy, chemical industry, construction, and other industries. Dolomite, as a non-metallic mineral resource with great economic value and can be developed and utilized in multiple ways, is of great significance to adhere to the fine processing and efficient and reasonable utilization of dolomite.
Glass products
Dolomite can also provide Calcium oxide in the glass industry, add soda ash silica system, and act as a flux. In addition, dolomite can also reduce glass aging, improve the plasticity of colored glass, and increase glass strength.
Metallurgical industry
1. Magnesium smelting industry: Dolomite with a particle size of 30-120mm is an important raw material for the production of metallic magnesium. Its smelting methods are mainly divided into two categories, namely electrolysis method and silicothermic reduction method.
2. Refractory: As one of the important raw materials of alkaline refractory, dolomite is second only to Magnesite in importance. It is mainly used for steel converter lining, open hearth, electric furnace wall, followed by thermal equipment such as external refining device and cement kiln.
Building materials industry
Manufacturing magnesium oxychloride cement is another important use of dolomite. This magnesium containing cement has good compressive, flexural strength, and corrosion resistance properties. Especially the caustic powder prepared by flame retardant calcination of dolomite, which is then used to prepare magnesium oxychloride cement, has better stability.
agriculture
Used to neutralize acidity in soil. Due to the long-term use of fertilizers such as urea, which can easily cause soil acidity, dolomite can be directly added to urea to maintain an appropriate pH value, generally increasing crop yield by 15% to 40%, and also improving the efficacy of herbicides.
ceramics
The use of dolomite in the raw materials and glazes, and the addition of dolomite to the glaze makes it less likely to smoke and rarely causes crystallization. This is due to the fact that dolomite is a complex salt mineral. The dolomite limestone mixture mixed by dolomite and Marl can be used to produce Anorthite and Diopside Wollastonite clinker, which is suitable for fast firing porcelain. In the manufacture of wall tiles and fine ceramics, the cost of this clinker is lower than that of the calcium Magnesium compounds synthesized separately.
The LM vertical roller mill of Liming Heavy Industry has stable product performance, smooth operation, high efficiency, large output, and high degree of automation, making it an ideal choice for achieving large-scale processing of dolomite. resources, and the proven reserves can meet the needs of economic construction.
