*High-Speed, Dust-Tight Packaging for Cement, Sand & Gypsum (25kg Bags)*
Shanghai Guangzhi Automation’s GZ-OMF3000 Series revolutionizes 25kg powder packaging with ±0.2% weight accuracy and 15 bags/minute throughput. Designed for abrasive materials like cement, sand, and gypsum, this ISO/ATEX-certified system integrates automated bag placement, filling, sealing, and dust control – slashing labor by 90%, eliminating spillage, and ensuring OSHA-compliant operation in harsh industrial environments.
Precision Gravimetric Filling
Loss-in-Weight Technology: Servo-controlled augers + load cells compensate for density variations (±0.2% accuracy).
Anti-Bridging Vibrators: Prevent material clumping in cement/gypsum with pulsed aeration.
Dust-Free Operation
Closed-Loop Filling Chamber: HEPA filtration (<1 mg/m³ emission) with automatic pulse cleaning.
ATEX Zone 22 Option: Explosion-proof design for combustible dusts (e.g., gypsum fines).
Automated Bag Handling
Robotic Bag Placers: Auto-open/sew woven PP bags (W: 40–60cm, H: 80–100cm).
Intelligent Clamping: Adjusts to bag thickness (150–300 gsm) without tearing.
Abrasion-Resistant Durability
Tungsten-Carbide Augers: 3× lifespan vs. steel in cement/sand applications.
Impact-Resistant Liners: Ceramic-coated contact points for silica abrasion.
