Principal Applications

  • Nanoparticle milling
  • Preparation of ultra-fine nanoparticles
  • Preparation of coatings
  • Preparation of dispersions
  • Preparation of emulsions

Advantages

  • High purity
  • Exceptional wear resistance
  • Minimizes contamination
  • Maximizes particle size reduction
  • Creates nanoparticles less than 100 nm
  • Highly efficient
  • Scalable
  • Low media density; enables high media loads and agitation speeds
  • Uniform particle size; prevents screen binding
  • Generates less heat than traditional media

Systems
