Particle Concentration Device (Dry Powder)

Utah State University seeks a company interested in commercializing a particle sorting device. The particle sorting equipment manufacturing market is a $48 million dollar market, which experiences a 3% annual growth rate. Market estimates for the particle sorting service industry range from $15 to $20 million. Controlling particle size is of great value in many industries. Particle size largely determines product quality, process efficiency, stability, and material strength. The particle sorter from USU offers a capability that other air classifiers are incapable of—the ability to simultaneously sort dry powders into multiple size fractions. The technology could not only provide a competitive advantage over competitors, but it could be inserted into an in-line process—making the overall process leaner. The system is also customizable, allowing users the option of tailoring the particle size distribution according to the application.
Features and Benefits
  • Chemicals
  • Pharmaceuticals
  • Minerals
  • Catalysts
  • Food Ingredients
  • Metal powders
  • Glass bubbles
  • Particle concentration


  • No impact sorting, resulting in less particle degradation and less waste
  • Ability to capture multiple size particles at once, allowing for a single stage process
  • Extremely accurate cut sharpness, giving high quality products
  • Removes particles that are above and below specific particle size distributions, eliminating costly waste
The particle sorter uses fluid dynamics to turn a jet stream containing particles. The particles separate according to size and density and are captured further downstream. The sorter requires no physical contact with the particles, which preserves particle quality and shape. Multiple capture bins can be set up downstream to capture multiple particle sizes simultaneously . The technology works best when capturing varying distributions within a 1-100 micron range.
Development Stage
Multiple prototypes have been developed and several validation tests have been conducted. Tests have proven competitive accuracy and competency. Multiple types of particle powders have been sorted with varying sizes and densities.
