Instructors: Joseph Marinelli, Solids Handlings Technologies, Inc.
9:00 AM - 12:00 PM
Bins & Hoppers: The Basics
Topics include:
  • Bin flow problems and their results
  • Flow patterns – funnel flow, mass flow, expanded flow
  • Flow properties testing – cohesive and wall friction properties
  • Design principles for reliable flow – flow/no flow criterion
  • Calculation of critical bin dimensions, opening sizes, wall angles, etc.
  • How to interpret a Flow Report
  • Examples of new designs that can be used by attendees
  • Approaches to retrofitting existing bins
