Our inclined screw packaging machine is an industrial-grade automatic bagging system designed for precise, high-speed filling of powder, granular, and dry bulk materials into valve bags, open-mouth bags, and big bags. Engineered and manufactured at our source factory, each unit combines a programmable weighing system, multiple valve-port configurations, and a robust mechanical drive to deliver consistent, dust-free performance across demanding production environments.

From putty powder and dry mortar to desiccants and cement-based construction materials, our automatic pneumatic packaging machines adapt to a wide range of material types. The machine’s modular architecture means buyers can configure the filling head, discharge mechanism, and sealing method to match the specific flowability and packaging requirements of their product : without paying for capabilities they do not need.

Machine Overview and Key Specifications

The inclined screw (single helix) conveying mechanism lifts material from a lower hopper to the filling spout at a precise, controllable feed rate. This design is particularly effective for low-density, poorly flowing powders that would bridge or segregate in vertical gravity-drop systems. The inclined orientation keeps the material in constant agitated motion, preventing compaction and ensuring consistent bag weights per cycle.

Standard performance parameters include:

•       Filling capacity: 4–8 bags per minute (material and bag size dependent)
•       Weighing accuracy: ±0.1–0.2% of target fill weight
•       Bag weight range: 10 kg to 50 kg per bag (25 kg single helix standard)
•       Compatible bag types: valve bags, open-mouth bags, big bags (FIBC)
•       Control system: PLC with touch-screen HMI interface
•       Dust suppression: integrated dust collection port on filling head
•       Power supply: 380V / 50Hz (customizable to regional standards)

Valve Port and Filling Head Configurations

One of the key differentiators of this machine line is the range of interchangeable valve port and bag-opening systems. Different bulk materials : ranging from fine desiccant powder to coarse construction aggregate : require different filling mechanisms to achieve reliable bag seating, minimal dust escape, and repeatable weight accuracy. The following configurations are available as selectable options:

1. Pneumatic Valve Port

Air-actuated bag clamping and release. Ideal for high-speed lines where rapid, consistent bag cycling is required. Suitable for free-flowing powders and granules.

2. Ultrasonic (Sealing) Valve Port

Combines filling and sealing in a single station. The ultrasonic head bonds the bag valve shut immediately after filling, eliminating product spillage during palletizing and transport. Recommended for moisture-sensitive materials such as desiccants and wall putty.

3. Impeller Type / Air Floatation Type

The impeller creates a fluidised air-powder mixture at the filling spout, allowing dense or cohesive powders to flow freely into the bag under air pressure. The air floatation variant suspends ultra-fine particles in an airstream for contact-free transfer, reducing compaction inside the bag.

4. Spiral (Screw) Valve Port

A rotating auger screw controls volumetric flow rate from the spout directly into the valve bag opening. Offers tight dosing control for materials with irregular flow behaviour.

5. Screw Opening (Bag Inserter)

An automated bag-placement mechanism accepts pre-stacked open-mouth bags from a magazine and presents them to the filling spout, enabling fully unattended operation on high-volume lines.

6. Gravity Valve Port

Relies on the material’s own weight and flow characteristics. Low-maintenance, low-power option suited to free-flowing granular products where filling speed requirements are moderate.

7. Gravity Opening

Gravity-fed bag presenter for open-mouth sacks. Simplest and lowest-cost opening mechanism, appropriate for semi-automatic configurations.

8. Belt Type Opening

A motorised belt conveyor positions and stabilises the bag beneath the filling spout. Suited to heavier bags and large-format sacks where pneumatic holding alone is insufficient.

9. Big Bag (FIBC) Option

An overhead support frame with hook or loop connection accepts 500 kg to 2,000 kg bulk bags. The same weighing and screw-feed system used for smaller valve bags controls the fill weight, maintaining accuracy at larger scales.

Supported Materials and Industries

This automatic powder weighing and bagging machine has been deployed across a broad range of industries. Common materials include:

• Construction materials: wall putty, dry mortar, cement-based homogeneous board mix, tile adhesive
• Chemical powders: desiccants (silica gel, molecular sieve), calcium carbonate, talc
• Industrial minerals: barite, kaolin, wollastonite, fly ash
• Agricultural inputs: fertiliser blends, trace mineral powders
• Food and feed adjacent: starch, flour blends, animal feed additives (food-grade variants available

Different materials will perform best with different valve port and opening configurations. Our engineering team assesses bulk density, particle size distribution, moisture sensitivity, and target throughput before recommending a specific machine variant.
