Read the answer →

What normally controls the result?

Reliable dosing depends on flow behaviour, bulk density, aeration, particle size, feeder control and the product drop into the pack.

  • Bulk density and aeration
  • Hopper geometry and agitation
  • Auger, vibratory or weigh-feeder setup
  • Drop height and dust containment
  • Pack support and product settling

Information that makes a recommendation more accurate

  • Representative product sample
  • Bulk density range
  • Particle or piece size
  • Target weight and tolerance
  • Pack dimensions and opening
  • Dust, hygiene and cleaning requirement
