PP Woven Bag Raffia FIBC Jumbo Bag Washing Recycling Line
Turnkey continuous washing and decontamination systems engineered to process heavily soiled PP woven sacks, raffia bags, FIBC bulk containers, and post-agricultural films into ultra-clean, dry flakes ready for extrusion pelletizing.
- Anti-winding shredding architecture prevents filament entanglement.
- Multi-stage friction washing and density separation eliminate sand and residual chemicals.
- Mechanical squeezing press combined with thermal drying reduces moisture below 3–5%.
- Modular layouts from 500 kg/h up to 3,000 kg/h with closed-loop water treatment.
Line Layout & Engineering Drawing
Process Layout Reference
This layout drawing illustrates a typical automated plastic film and woven bag washing line configuration. Equipment arrangement (straight-line, L-shaped, or U-shaped) is engineered to match your factory footprint, ceiling heights, contamination levels, and production targets.
Key Technical Features
Advanced washing, friction shearing, and density separation technologies engineered for tough post-industrial and post-consumer bag waste.
-
Ultra-High Purity Output
Intensive high-speed friction washers and multi-channel sink-float tanks strip heavy soil, cement, inks, and adhesives.
-
Anti-Entanglement Design
Heavy single-shaft shredders and wet granulators are equipped with wear-resistant knives and anti-winding guards for continuous flow.
-
Deep Dewatering Efficiency
Mechanical screw squeezer press followed by hot-air pipe drying guarantees moisture <3–5%, saving pelletizer extruder energy.
-
Closed-Loop Water Management
Seamless integration with DAF dissolved air flotation systems allows up to 90% water recycling, reducing wastewater discharge.
Typical Feedstock Applications
Engineered for a broad spectrum of rigid and flexible woven polyolefin packaging materials.
-
PP Woven Bags & Sacks
Post-industrial grain sacks, sugar bags, and chemical fertilizer woven packaging.
-
FIBC Jumbo Bags
Heavy 1-ton and 2-ton flexible intermediate bulk containers with heavy lifting straps.
-
Agricultural Mulch & Greenhouse Films
Severely soiled agricultural LDPE films containing up to 40% sand and mud contamination.
-
Cement & Mineral Bags
Coated and laminated multi-wall woven sacks with stubborn mineral dust encrustation.
Working Principle: Step-by-Step
Fully automated, PLC-controlled system with seamless material conveyance between reduction, washing, and drying stations.
1. Bale Breaker + Single-Shaft Shredder
Opens densely compacted bales and pre-shreds bulky FIBC sacks into loose 50–100 mm strips with anti-tangling rotor geometry.
2. Wet Granulator Pre-Washing
Reduces pre-shredded strips down to uniform 15–25 mm flakes while continuous water injection pre-washes away abrasive grit.
3. High-Speed Friction & Hot Wash
High-speed rotary paddles scrub flakes against perforated screens to strip stubborn surface printing inks, grease, and glues.
4. Sink-Float Separation Tank
Heavy stones, cement, metals, and glass sink to the bottom auger while clean floating PP/PE flakes are paddle-conveyed forward.
5. Mechanical Screw Dewatering
Continuous mechanical squeezing press expels surface water and compresses light film volume, lowering moisture below 10–12%.
6. Thermal Pipe Drying & Cyclone
Hot air pneumatic drying duct flashes off residual moisture, delivering clean, dry flakes with final moisture <3% into the cyclone.
7. Storage Silo → Pelletizing Line
Dry, purified flakes are pneumatically fed into buffer storage silos, ready for water-ring or strand pelletizing extrusion.
