Automatic Bagging Machine Manufacturer & Supplier

The standard choice for granule and free-flowing powder applications where declared weight accuracy matters — grain, fertiliser, plastic pellets, salt, sugar. Net weight systems weigh the product before bag entry; bag weight variation has zero effect on fill accuracy. Output range 400–1,800 bags/hour depending on product flow rate and bag weight. The ±0.2% accuracy figure assumes product bulk density above 450 kg/m³ and free-flow rating above 60 seconds (Hall flowmeter) — products outside this range need pre-testing.

Lower cost than net weight systems; suitable for 25–50 kg industrial bags where ±2g bag weight variation is negligible (0.008% of fill weight). Not recommended for bags below 5 kg where tare variation becomes significant relative to fill weight.

Purpose-built for fine powders with bulk density below 600 kg/m³. Dust-tight construction, impeller or screw filling mechanisms. Standard auger fillers block on fine powder — this design addresses that failure mode specifically.

For PP woven, PE and multi-wall paper bags requiring clamp-and-fill rather than valve injection. Faster bag changeover than valve systems; better suited to products with moisture content that would clog a valve spout.

For cement, chemical powder and gypsum requiring a fully enclosed, dust-free bag after filling. Valve bags self-seal after spout withdrawal — no additional sealing station. Rotary configurations for throughput above 600 bags/hr.

Complete turnkey lines: filler, checkweigher, conveyor, sealer, labeller, palletiser. For producers moving from semi-automatic to lights-out packaging. PLC integration with Siemens or Allen-Bradley standard.

Hopper receives product from silo or bulk bag. Agitators prevent bridging in cohesive or sticky materials.

⚠ Most speed losses originate here. Hopper geometry must match product flow characteristics — not a standard design.

Product measured by weight (load cell, net or gross) or volume (auger or piston). Net weight systems verify dose before bag entry — the bag never receives an incorrect weight.

Bag picked, opened and clamped at spout. Product discharged in controlled flow. Fill speed is the product of metering rate and bag clamp dwell time — both adjustable.

⚠ Bag opening failures account for 40–60% of unplanned stoppages on standard machines. Discuss your bag supplier before confirming a machine.

Bag sealed by heat seal, sewn top, tape or self-seal valve. Downstream checkweigher confirms fill weight. Conveyed to palletiser or manual stacking area.

Multi-head weigher systems dominate this segment. Key variables: seasonal throughput peaks, strict declared-weight regulations, and HACCP-compliant contact surfaces for food applications.

Granule and prilled fertiliser runs well on standard multi-head weigher designs. Corrosive products (ammonium nitrate, potassium chloride) require specific material specifications for contact parts.

Often requires ATEX-rated components and material compatibility review before any machine is specified. Dust containment is not optional — it is a safety requirement in most jurisdictions.

High-volume abrasive duty. Standard machines last 3–6 months before wear requires replacement. Cement-specific designs with hardened wear liners and sealed bearing housings are the correct specification.

Product range within one facility is the challenge: fine meal, crumble, pellets from 2mm to 12mm often on the same line. Changeover time under 15 minutes between bag sizes is achievable with the right design.

Standard multi-head weigher or belt weigher designs work well. Key consideration: static charge buildup on plastic pellets can cause bag adhesion and bridging — discuss with us before specifying.

Every enquiry goes to an applications engineer before a quote is generated. We have declined orders where the machine type requested would not work for the product described. That costs us short-term revenue and builds every long-term relationship we have. If your product has unusual flow characteristics — tell us. We have a physical test lab and run samples before confirming the design.

Custom specifications — non-standard bag dimensions, explosion-proof zones, modified hopper geometry, integration with existing conveyors — are designed into the machine from the start, not added after a standard machine is built. Off-drawing retrofit always means compromises. We work from your facility layout drawings.

Every machine ships with an operator manual, video commissioning guide and spare parts list for the first 2,000 operating hours. Remote video commissioning is included at no charge. On-site engineers are available for complex multi-machine line installations. We don’t consider a sale complete until the machine is running at specification.

CE marking requires a complete technical file: Declaration of Conformity, risk assessment, circuit diagrams, O&M manual. We provide the full package in English — not a single-page CE certificate. For EU imports this reduces customs clearance time and eliminates requests for supplementary documentation that delay delivery.
