🔹 Valve Bag Packaging & Palletizing Lines (×2)
• Finished product hopper — alloy steel closed silo with dust collection, breathing system, and pneumatic vibrator for anti-arching
• Valve bag packaging machine — impeller / air blowing / air floating types available, weighing accuracy ±0.2%
• Bag flattener — presses each bag flat for stable stacking
• Column palletizer (mini palletizer) — compact size, PLC-controlled, ~500 bags/hour, flexible palletizing patterns
• Pallet wrapping machine — finished pallets transported to wrapping station, stretch film wrapped around stacked products




🔹 Big Bag Packaging Line 1
• Pulse dust collector — high purification efficiency, low emission concentration, stable performance
• Ton bag packaging machine — 200-2000kg per bag, 20-40 bags/hour, accuracy ±2‰-5‰


🔹 Big Bag Packaging Line 2 (Full Process)
• Main material hopper — receives raw sand
• Belt conveyor with magnetic separator — removes metal impurities during transport
• Bucket elevator — vertical transport to platform
• Vibrating screen — screens sand by particle size (0.63mm / 1.2mm / 2.0mm mesh), unsuitable sand diverted to separate bags via pipes
• Product hopper — stores qualified sand
• 2× ton bag packaging machines — simultaneous filling
• Workflow: Raw sand → main hopper → belt conveyor (magnet removes metal) → bucket elevator → vibrating screen → qualified sand to product hopper → 2 ton bag fillers
