Powder behaviour
Why bulk density matters when specifying a powder filler.
Bulk density affects how much product is delivered for each auger rotation and how stable the dose remains during production.
Practical guidance
Start with the product, pack and required output.
Two powders with the same target weight can need different screws because they occupy different volumes. A light, aerated powder may need more volume and careful settling, while a dense powder may need a smaller screw and stronger control over cut-off.
Bulk density can also change during handling. Vibration, conveying and hopper level can compact or aerate product, which is why product testing should reflect the way the material will be loaded on the real line.
Details that help narrow the specification
- Loose and tapped density figures
- How the product is fed to the hopper
- Fill weight and available headspace
- Settling before closing or sealing
- Whether checkweighing is required
Buying decisions
Points to confirm before choosing equipment.
These checks help compare semi-automatic, automatic and line-integrated options against the way the product will actually be packed.
Make sure product reaches the auger consistently without bridging, compaction or operator bottlenecks.

Quick answers
Common questions from machinery buyers.
What bulk density figure should I send?
Send loose and tapped density if available, along with a representative sample.
Can density changes affect weight?
Yes. If volumetric dosing is used, density variation can change the weight delivered.
Is this only important for light powders?
No. Dense and granular products can also require different auger tooling and cut-off settings.
Send the product and pack details.
We can help compare the auger filler, powder feed and line options that fit your production requirement.
