Open-Mouth Bag Filling Machine 🔹 What It Is An open-mouth bag filling machine is designed to automatically weigh, fill, and seal pre-made bags with powders, granules, or small solids. It is widely used in chemicals, food, feed, fertilizer, and building materials industries. 🔹 How It Works Bag Supply & Picking – Pre-made bags are loaded into a magazine; the machine automatically picks and positions each bag. Bag Opening & Clamping – Bag mouth is opened with vacuum/air or mechanical clamps for a tight, dust-free seal around the filling spout. Weighing & Filling – Coarse fill followed by fine fill with high-accuracy load cells (±0.2%). Bag Settling / Vibration – Optional densifying vibration to remove air pockets for consistent weight. Sealing / Closing – Bags are sewn, heat-sealed, or ultrasonically sealed. Discharge – Filled bags move onto conveyors for palletizing. 🔹 Applications Powders: cement, flour, gypsum, chemicals, carbon black Granules / Pellets: fertilizer, feed, rice, sugar Other Materials: seeds, minerals, small aggregates 🔹 Key Features Bag Size: 5–50 kg (standard) Bag Types: paper, PE, PP, laminated, with or without liners Speed: 6–18 bags/min (single spout); multi-spout versions up to 120+ bags/min Accuracy: ±0.2–0.5% depending on product Dust Control: enclosure, aspiration ports, optional explosion-proof design Automation: PLC control with HMI, recipe storage, remote monitoring options 🔹 Advantages ✅ High-speed, fully automatic operation ✅ Precise filling reduces product loss ✅ Dust-free, clean, and safe operation ✅ Handles multiple bag sizes and materials ✅ Easily integrated with palletizing and wrapping systems 🔹 Optional Upgrades Multi-spout carousel for higher throughput Vibration or tamping for better bag density Automatic bag positioning and weight correction Metal detector and checkweigher integration ATEX-compliant for explosive dust environments
