Introduction to 10-50 kg Open Mouth Bag Filling Machine
The 10–50 kg open mouth bag filling machine is a dependable solution for dosing powders, granules, and blends into pre-made sacks with tight weight control. Indian processors in food, fertiliser, chemicals, and minerals rely on PLC-based weighment, rugged frames, and integrated stitching or heat sealing for hygienic, repeatable output. Modern lines support gravity, belt, and screw feeders to match different flow behaviours, while dust extraction improves housekeeping and safety. For application guidance, layouts, and commissioning support, explore trusted Indian partners such as Samirika Group to select the right configuration, spout, and peripherals for capacity expansion or upgrades.
Working Principle and Process Flow for 10-50 kg Open Mouth Bag Filling Machine
Operation begins with bag hanging on a pneumatically clamped spout and capturing tare. Product feeds via gravity, belt, or auger screw, depending on flowability. High-resolution load cells signal a PLC to manage coarse and fine dosing, achieving precise cut-off near the setpoint. After weighment, the bag releases to a conveyor for stitching with crepe tape or heat sealing for laminated sacks. Dust extraction at the mouth maintains hygiene and visibility.

Types of 10-50 kg Open Mouth Bag Filling Machines
- Gravity-feed bag filling machine for free-flowing rice, sugar, pulses, and salt, delivering fast cycles with low maintenance.
- Belt-feed bag filler for fragile or aerated granules and prills, ensuring steady dosing where gravity systems surge or bridge.
- Auger-screw bag filling system for fine, cohesive powders like flour, minerals, and additives requiring controlled, dust-limited feed.
- Fully automatic line with bag placer, weighment, sealing or stitching, rejects, conveyors, and data connectivity for Industry 4.0.
- Compact semi-automatic station supporting manual bag hanging, automatic clamping, coarse–fine dosing, weight cut-off, and conveyor takeaway.
Key Features and Specifications of 10-50 kg Open Mouth Bag Filling Machine
- PLC with high-resolution load cells delivers precise coarse–fine cut-off and repeatable, traceable net weights.
- Rugged, powder-coated frame and sealed bearings withstand abrasive products and dusty Indian plant conditions.
- Tool-less spout adjustments cover common sack sizes and liners, reducing changeover time between SKUs.
- Interfaces for printers, sealers, stitchers, metal detectors, and checkweighers enable turnkey line integration.
- Dust extraction ports and enclosures improve hygiene, housekeeping, and operator visibility at the filling mouth.
Applications of 10-50 kg Open Mouth Bag Filling Machine
- Food mills packing rice, wheat, flour, sugar, and pulses for wholesale and HoReCa channels, requiring hygienic handling, barcode printing, rapid SKU changeovers, and accurate weights to maintain retailer confidence, export compliance, and stable pallets during long-distance distribution across India.
- Fertiliser plants bagging urea, DAP, NPK blends, and micronutrients, demanding rugged mechanics, dust control, and reliable stitching to protect product quality, reduce wastage, and sustain pallet integrity through warehouse stacking, intermodal transport, and rural supply chains in varied climates.
- Minerals and construction materials like silica sand, gypsum, fly ash, and refractory fines, where precise dosing, sealed closures, and robust conveyors minimise spillage, protect workers, and deliver consistent stacks for storage yards, depots, and infrastructure projects nationwide.
- Chemicals and detergents including catalysts, additives, soda ash, and detergent powders, needing tamper-evident closures, traceable labels, and accurate net weights, while integrating printers and checkweighers to improve audits, reduce claims, and streamline contract manufacturing workflows for diverse customers.
Benefits of Using 10-50 kg Open Mouth Bag Filling Machine
- Tighter accuracy reduces giveaway and rework by controlling coarse and fine dosing precisely, producing consistent bag weights that protect margins, simplify inventory reconciliation, and build distributor confidence through predictable pallet counts and fewer customer claims across tenders.
- Higher throughput from automated clamping, indexing conveyors, and integrated sealing or stitching lifts daily output, enabling shorter lead times, better OEE, and reliable shift planning, even with frequent recipe changes and multi-SKU schedules across seasonal demand fluctuations.
- Lower operating costs arise from dust control, robust frames, and straightforward preventive maintenance, reducing spares consumption and unplanned stoppages; tool-less spout changes and quick calibrations minimise downtime, improving total cost of ownership for SMEs and large processors alike.
- Improved compliance via batch coding, tamper-evident closures, and traceable weighments strengthens audits and export readiness, enhances brand reputation, and supports FSSAI and BIS expectations while enabling data capture for dashboards, analytics, supplier scorecards, and continuous improvement.
