Barite is an important barium-containing mineral, with large specific gravity (4.3-4.7), low hardness (3-3.5), stable chemical properties, insoluble in water and acid, barite can be used as a white pigment (commonly known as Lide It can also be used in chemical, paper, textile filler and other industrial sectors. In glass production, it can act as a flux and increase the brightness of glass, of which 80%-90% is used as a mud weighting agent in oil drilling.
Barite crusher and processing process
According to the downstream industry demand after barite processing and grinding, 325 mesh and its finer ultra-fine powder barite have a good market, and the processing technology of this particle size range has also become the mainstream technology of barite processing.
- The large barite blocks are first crushed by a small jaw crusher or an impact crusher to suit the feed size of the pulverizer.
- After crushing, the materials with suitable particle size are sent to MTW trapezoid mill or medium-speed trapezoid mill, LM vertical mill and other barite grinding equipment.
- The barite block particles are ground and classified in the pulverizer. The qualified powder is collected after passing through the classifier, and the unqualified powder is re-ground.
- Packaging and storage of finished materials
Barite grinding mill equipment
For non-superfine barite powder, MTW European version trapezoidal barite mill is recommended; for superfine powder production line, T130X Superfine Grinding Mill is an ideal choice.
Investment prospects
Due to the special properties and cheap development cost of barite, people are paying more and more attention. Modern industrial development has put forward higher requirements for the purity, whiteness and particle size of barite. Therefore, with the continuous development of science and technology and the in-depth research of barite more The performance has been revealed. The deep processing of barite, ultra-fine powder, purification and surface modification only broadens the application field and has better economic benefits. There is a large demand in the domestic and foreign markets.
The main use of barite
- Mud weighting agent for drilling: At present, the main use of barite powder is for drilling mud weighting agent. The fineness should generally reach 325 mesh or more, the specific gravity should be greater than 4.2, the BaSO4 content should be 90% to 95%, and the soluble salt less than 1%.
- Zinc barium white pigment: Zinc barium white is a commonly used high-quality white pigment, which can be used as a raw material for paint and painting pigments. The barite for the preparation of zinc barium white pigment requires a fineness of at least 1250 mesh or more, the BaSO4 content is more than 95%, and the whiteness is generally required to be more than 90.
- Barium compound: barite as raw material can be used to manufacture barium oxide, barium carbonate, barium chloride, barium nitrate, precipitated barium sulfate, barium hydroxide and other chemical raw materials. The fineness requirement is generally around 800 mesh.
- Paint filler: barite powder filler can increase the thickness, strength and durability of the paint film. Zinc barium white pigment is also used to make white paint, which has more advantages than lead white and magnesium white in indoor use. The barite used in the paint industry requires a fineness of more than 2000 mesh and a whiteness of more than 95.
- Fillers in paper, rubber and plastic industries: This filler can improve the hardness, wear resistance and aging resistance of rubber and plastics. The requirements for fineness are generally between 500 meshes and 1250 meshes.
- Radiation-proof cement, mortar and concrete, etc.: This kind of use mostly uses the characteristics of large proportion of barite, and has low requirements on the content of impurities, basically no requirements on whiteness, and requires a specific gravity of 4.2 or more, and the fineness is generally 325 mesh.
