Powder Processing Technologies

Typical Characteristics of Powders

  • 1. Particle size
  • 2. Particle size distribution
  • 3. Particle shape
  • 4. Specific gravity and apparent powder density
  • 5. Particle surface design (specific surface area, porosity, wrinkles, etc.)
  • 6. Resin coating

The following technologies control the characteristics listed above.

a) Granulation Technology

Particles of different sizes and shapes are created using spray-drying (wet process), compression molding (dry process), rolling granulation (dry process), and other methods.

b) Classification Technology

Particle size distribution is adjusted using combinations of multiple methods such as sieving and air sifting.

c) Sintering/Heating Technology

Particle surface designs and inner structures are controlled using static heating, fluidized-bed heating, and other heating methods best suited for each material and purpose. This processing enables the structuring of hollow particles and a wide range of specific gravity (particle density) adjustments by modifying the surface texture.

d) Resin Coating Technology

Particles can be coated with different types of organic resin to provide flow properties, electrical characteristics, and other functions.

Powdertech creates diverse types of powders and particles by selecting and combining these technologies in various ways.
