Barite is an important non-metallic mineral raw material, with barium sulfate (BaSO₄) as the main component, and has a wide range of industrial uses. The following is a detailed introduction to barite:
Structural properties:
• Specific gravity: 4.0~4.6.
• Chemical composition: BaO accounts for 65.7%, SO₃ accounts for 34.3%. There may be homologous substitutions of Sr, Pb and Ca in the composition.
• Physical properties: Pure barite appears white and shiny, but it often appears gray, light red, light yellow, etc. due to the influence of impurities and mixtures. Barite with good crystallization conditions can also appear as transparent crystals. When it is pure, it is colorless and transparent. When it contains impurities, it is dyed into various colors. It has a glassy luster and is transparent to translucent.
• Hardness and cleavage: Mohs hardness 3 to 3.5, three groups of complete cleavage, and the included angle is equal to or close to 90°.
Barite grinding equipment is a special equipment used to grind barite ore into fine powder. When selecting barite grinding equipment, factors such as production scale, output, discharge particle size, fineness, uniformity, degree of automation, environmental protection requirements, and after-sales service need to be considered.
The following are some common barite grinding equipment:
1. Raymond mill: Raymond mill is a commonly used grinding equipment. It has the advantages of compact structure, small footprint, low energy consumption, low noise, and easy operation. It is suitable for medium and small scale barite grinding production lines.
2. Vertical roller mill: The vertical mill is an efficient and energy-saving grinding equipment with the characteristics of high grinding efficiency, low energy consumption, low noise, and small footprint. It is suitable for medium and large-scale barite grinding production lines.
3. European version of trapezoidal grinding equipment: If you need to obtain ultra-fine barite powder, you can choose an ultra-fine grinding mill. This type of equipment produces finer, more uniform powders, but typically also has a higher investment cost.
For the 38 t/h barite grinding production line in Uzbekistan, the following is a basic planning and equipment selection suggestion:
1. Production line planning
• Raw material preparation: Ensure the supply and quality of barite raw materials, and conduct preliminary screening and impurity removal.
• Crushing: Use a jaw crusher or other suitable crushing equipment to break large pieces of barite to a size suitable for grinding.
• Grinding: This is the core part of the production line. Efficient and stable grinding equipment, such as MTW mill or vertical mill, etc., are used to grind the crushed barite into powder with the required fineness.
• Classification: Use a powder classifier to classify the ground materials to ensure that the particle size of the powder meets the requirements.
• Collection and packaging: Collect qualified powder for packaging or storage.
2. Equipment selection
• Crushing equipment: According to the size and hardness of the raw materials, select suitable crushing equipment, such as jaw crusher, impact crusher, etc.
• Grinding equipment: Considering the output of the production line and the fineness requirements of the powder, you can choose MTW mill, vertical mill or ultra-fine vertical mill, etc. These equipments have the advantages of high efficiency, stability, environmental protection, etc., and can meet production needs.
• Classification equipment: Use an efficient powder separator for classification to ensure that the particle size of the powder meets the requirements.
• Other auxiliary equipment: including electromagnetic vibrating feeders, bucket elevators, storage bins, pipeline devices, blowers, etc. These equipment can ensure the continuous and stable operation of the production line.
3. Precautions
When selecting equipment, factors such as the characteristics of the raw materials, the output of the production line, and the fineness requirements of the powder must be fully considered to ensure the matching and adaptability of the equipment.
In the layout and design of the production line, factors such as equipment installation, debugging, and maintenance must be fully considered to ensure the smooth operation of the production line.
During the production process, operating procedures and safety regulations must be strictly followed to ensure production safety and product quality.
In short, for the 38 tons/hour barite grinding production line in Uzbekistan, it is necessary to select appropriate equipment and carry out reasonable planning to ensure the stable and efficient operation of the production line.
