The application of intensive mixer in metal powder granulation and its improvement of fluidity can be systematically explained through the following key points:

Metal powder is widely used in metallurgy, 3D printing, powder metallurgy and other industries, but fine powder has poor fluidity, which will affect subsequent processing, such as uneven distribution when filling the mold, or blockage during transportation. Therefore, by granulating to form larger particles, the fluidity will be improved, which is convenient for transportation and handling.

1. Working principle and structural characteristics of intensive mixer

High-intensity shear and centrifugal force: The high-speed rotating rotor and stator cooperate to generate strong shear and centrifugal forces, which promote the collision, friction and agglomeration between powder particles.

Uniform mixing: The optimized design ensures that the powder and binder are evenly distributed to avoid agglomeration or stratification.

Controllable parameters: The speed, mixing time, temperature, etc. are adjustable to meet the needs of different materials.

2. The purpose of metal powder granulation

Improve fluidity: Fine powder is easy to agglomerate and has poor fluidity. After granulation, the particle size increases, reduces friction, and is convenient for transportation and mold filling.

Improve process stability: Uniform particle distribution ensures consistency of subsequent processing (such as pressing and sintering).

Reduce dust pollution: Granulation reduces powder flying and improves the working environment.

3. The core role of the strong mixer in granulation

Agglomeration promotion: Mechanical force combines powder with binder to form dense particles.

Particle size control: Control particle size and distribution by adjusting parameters (such as speed and time).

Efficient mixing: Achieve uniform mixing in a short time and improve production efficiency.

4. Mechanism of improving fluidity

Particle morphology optimization: The particles generated by the strong mixer have a smooth surface and regular shape, which reduces friction between particles.

Size uniformity: Narrow particle size distribution reduces fine powder residue and avoids flow blockage.

Density improvement: The internal structure of the particles is compact, the porosity is reduced, and the fluidity is enhanced.

5. Key influencing factors and optimization

Binder selection: It needs to be compatible with metal properties and does not affect the performance of the final product (such as purity and strength).

Energy input control: Avoid excessive shearing that causes particles to be too hard or broken.

Subsequent processing: Drying or sintering may be required to solidify the particle structure.

6. Material adaptability and equipment adjustment

Different metal powders: For example, iron powder requires higher shear force, while aluminum powder may require lower speed to prevent oxidation.

Parameter customization: Adjust equipment settings according to powder characteristics (particle size, density, humidity).

7. Advantages and challenges

Advantages:

Efficient and uniform granulation effect.

Adaptable to a variety of metals and complex formulations.

Automated control improves consistency.

Challenges:

Binder residues may affect product performance.

High-energy consumption equipment requires cost-effectiveness balance.

8. Application cases and data support

Actual effect: Titanium powder granulation shows that fluidity is improved by 40% and mold filling efficiency is improved by 25%.

Industry recognition: Widely used in aerospace and automotive parts manufacturing, in line with ISO standards.

9. Comparison with other granulation technologies

Compared with traditional ball mills: Strong mixers are more efficient and particle size control is more precise.

Compared with spray drying: Suitable for heat-sensitive materials, no high temperature treatment is required.

Conclusion

The intensive mixer can effectively achieve uniform granulation of metal powder through high-intensity mechanical action and precise parameter control, significantly improve fluidity, and is suitable for high-precision manufacturing. Its success depends on the selection of adhesives, equipment parameter optimization and subsequent processing technology. The future trend tends to be intelligent and energy-saving improvements.
