Guangzhi’s valve bag filler packs cement/fertilizer at 20 bags/min with ±0.1% accuracy. ATEX-certified dust control & 90% labor reduction. Free engineering study!
*Precision, Dust-Free Packaging for Cement, Fertilizer & Bulk Powders (10–50 kg)*
Shanghai Guangzhi Automation’s GZ-VBF1000 Series redefines high-volume bagging with robotic valve sack handling, ±0.1% gravimetric accuracy, and closed-loop dust control. Designed for abrasive and hygroscopic materials, this ATEX/ISO-certified system fills 12–20 bags/minute while slashing labor costs by 90% and eliminating product loss.
Zero-Spill Filling
Smart Valve Sealing: Pneumatic clamps + inflatable spouts create dust-tight seal with valve sacks.
Multi-Stage Weighing: Gain-in-motion load cells ±0.1% accuracy, compensating for density shifts in fertilizers/cement.
Robotic Bag Handling
Auto Sack Placers: Pick/fill/seal valve bags (PP, jute, paper) without manual intervention.
Bag Shaking System: Compacts material for 5–8% higher packing density.
Industrial Durability
Abrasion-Resistant Contact: Tungsten-carbide coated augers/fillers for cement/silica (service life 3× industry avg).
Corrosion-Proof Build: 316L SS + PTFE liners for acidic fertilizers (pH 1.5–12).
Dust Containment
Negative Pressure Hood: HEPA filtration (<1 mg/m3 emission) with automatic pulse cleaning.
ATEX Zone 22 Option: Explosion-proof design for combustible dusts (e.g., starch, sulfur).
