Shanghai Guangzhi Automation’s Open Mouth Bag Filler is engineered for high-speed filling of sand, gypsum, cement powders into 10kg open-mouth bags (PP woven/composite film). Combining dynamic weighing (±0.3% accuracy), ATEX-certified dust control, and automated stitching, it achieves 12-15 bags/minute while reducing labor costs by 60% and dust emissions by 99.5%.
1. Precision Weighing & Filling
Dynamic ±0.3% Accuracy: Triple-load-cell weighing system adapts to powder flow variations (≥50 mesh ultrafine to coarse granules).
Two-Stage Dust Control: Vortex air seal + negative pressure recovery (≥99.5% efficiency), compliant with OSHA/ATEX Zone 21.
2. Fully Automated Operation
Smart Bag Positioning: Photoelectric sensors auto-align bags; integrated clamping, filling, compaction, and stitching.
Quick-Change System: Switches between sand/gypsum/cement in <5 mins with <0.1% residual carryover.
3. Industrial Robustness
304L Stainless Steel + Polyurethane Components: Wear-resistant design for corrosive environments (e.g., cement/chemical plants).
IP55 Protection: Dust/water-resistant motors and control cabinets (-15°C to 50°C operation).
