Cohesive powders, sticky mixes and products that bridge in the hopper need a filling route that keeps product moving without damaging fill accuracy. The auger, hopper and feed method need to be considered as one system.
Non-free-flowing powder fillers for cohesive, bridging or difficult powders requiring controlled auger dosing, agitation and hopper planning.

Send product detailsThese points help decide whether the best route is compact, semi-automatic, automatic, VFFS or a complete filling line.
Some powders bridge, some compact, some aerate and some smear around the nozzle. The machine choice should respond to the actual behaviour, not just the product name.
Agitation, geometry, product conditioning and screw feed can all affect whether the auger receives a stable supply of product.
Difficult powders can make dosing less stable. Weigh feedback, slower fill strategies or specific tooling may be needed where tolerance is tight.
Often yes, with suitable hopper design, agitation and dosing setup.
Bulk density, particle size, moisture, samples, photos, fill weight and current filling problems are useful.
Sometimes. The comparison depends on flow, accuracy, speed and product value.
Send your powder, pack and output target and we will help point you towards a suitable auger filling option.
Cohesive powders can bridge above the auger, form rat holes, compact around the agitator or discharge in irregular slugs. Stable dosing starts with hopper geometry, agitation, working level and refill method before the auger recipe is adjusted.
Observe whether a stable arch forms above the outlet or auger inlet.
Check whether a narrow flow channel leaves stagnant product at the hopper wall.
Use enough conditioning to feed the auger without overworking, heating or aerating the product.
Compare dose and flow near the agreed refill point rather than running the hopper empty.
Sequential weights are difficult to interpret if hopper level, agitation or refill events are not marked. The approved recipe should include the product-feed method and working-level limits.
Lancing can assess hopper conditioning, tooling and whether another dosing method should also be compared.
