Powder and piece fillingWhat information is needed to specify equipment for cohesive powders?
Practical guidance for cohesive powders: capture samples, dimensions, output, acceptance tests and site constraints before buying.
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
