Instructors: Eric Maynard, Senior Consultant, Jenike & Johanson
9:00 AM - 12:00 PM
Preventing Particle Segregation and Its Harmful Effect on Product Quality
  • Common mechanisms of particle segregation
  • Methods to quantify segregation tendencies (ASTM standardized segregation testers)

  • Sample collection, splitting, and analysis
  • Flow patterns within a bin or blender and their effects on particle segregation
  • Blending mechanisms
  • Types of blenders (ribbons, paddles, tumblers, rotary, contact-bed, tube blenders)
  • Sampling techniques (thief vs. discharge sampling)
  • Attendees’ questions
