Feeders are used to control the rate of bulk material discharge from a bin into a process. Without proper feeder design and implementation, costly problems such as erratic discharge, flooding, high power consumption, particle damage, or abrasive wear result.

The content covered in this webinar will help a participant to understand the fundamental principles involved in selecting an effective bulk solids feeder, such as a screw (auger), belt, or rotary valve (rotary airlock), and implementing the appropriate interface with a bin, hopper, or silo.

Some important points to be covered during the webinar:

  • Feeder vs. conveyor or discharger
  • Key hopper features and discharge patterns
  • Basic features of screws, belts, rotary valves
  • Proper interface between a feeder and a hopper
  • Power considerations for screws and belts
