Shanghai Guangzhi’s Open Mouth Bag Filler achieves ±0.3% accuracy for 25kg sand/compost at 10-12 bags/min. Dust-free operation & auto-stitching. CE/ATEX compliant.
Shanghai Guangzhi Automation’s Open Mouth Bag Filling Machine is engineered for precision filling of 25kg sand and compost soil. Featuring dynamic weighing (±0.3% accuracy), ATEX-certified dust suppression, and fully automated bag stitching, it delivers 10-12 bags/minute while cutting labor costs by 65%.
1. Ultra-Precise Weighing & Filling
Dynamic ±0.3% Accuracy: Triple-sensor load cells adapt to material density variations (sand: 1.4-1.6g/cm3; compost: 0.4-0.6g/cm3).
Zero Dust Emission: Vortex air seal + HEPA filtration (99.97% efficiency), compliant with ATEX Zone 21 (combustible dust) and OSHA standards.
2. Robust Heavy-Duty Design
Reinforced Stainless Steel 316L: Abrasion-resistant construction with 5mm wear plates for high-impact materials.
IP65 Protection: Sealed electrical components (-20°C to 55°C operation; 85% humidity resistance).
3. Fully Automated Workflow
AI Bag Alignment: LiDAR sensors auto-detect bag position; automated clamping, filling, compaction, and stitching.
Quick Material Switch: Change between sand/compost in <3 mins (residual carryover <0.1%).
4. Smart Integration
PLC + IoT Connectivity: Real-time data sync via Modbus TCP for ERP/MES systems.
Auto Print & Apply Labels: Integrated thermal printer for batch/weight data (QR/barcode).
