Product Description

Product Description

Chemical Fiber Fabric Recycling Granulation Production Line is suitable for processing high-strength, high-loft, easily-tangled polypropylene (PP) fiber materials:

PP Filament/Yarn: Polypropylene filament, industrial polypropylene yarn, multifilament yarn
PP Fiber Fabrics: Polypropylene non-woven fabric, carpet backing, geotextile
Baled Fiber Scraps: PP fiber waste and offcuts generated from spinning mills and weaving factories
PP Woven Products: Woven bags, FIBC (bulk bags), rope nets, etc.

‌Industrial scraps: Melt-blown fabric scraps (PP melt-blown fabric waste generated during mask production)

Recycling Process

Belt conveyor → Metal detector 1→ Double-single shaft shredder → Discharge conveyor → Buffer silo → Feed conveyor → Metal detector 2→ Screw compaction feeder → Extruder 1 → Single-plate dual-position screen changer → Extruder 2 → Large-area dual-column screen changer → Water-flow strand pelletizing → Vibrating sieve → Finished-product silo

The machine will make adjustments based on production factors such as actual output, and the picture shows a customized production line example.

Product Details

1. Double-Single Shaft Shredder (PNDS-1000D) — Fiber Cutting with Water-Cooled Shafts

Shredding is the make-or-break station. The PNDS-1000D was uprated specifically for this project:

Feature	Specification
Motor power	Upgraded to 55 + 55 kW with No. 7 gearbox (standard: 45 + 45 kW / No. 6)
Tool steel	DC53 die steel; tungsten steel or HSS optional
Rotor knives	Four-edge design — each corner can be indexed, reducing maintenance by 80%+
Stator knives	Symmetrical top/bottom and left/right; four faces can be reground, cutting tool cost by 75%+
Shaft gap	CNC-machined to extremely tight tolerances to prevent fiber wrapping
Shaft cooling	Circulating water keeps shafts at 30–40 °C, preventing melt-wrap and maintaining full-load output
Output size	30–80 mm, ideal for downstream screw compaction

2. Screw Compaction + Enlarged Screw — Replacing 160 kW with 5.5 kW

After shredding to 30–80 mm, the material is still fluffy but no longer stringy. A 5.5 kW screw compactor forces it into the extruder feed throat. This single substitution saves nearly 160 kW in the feeding stage alone.

To match the high feed rate, Extruder 1 was upgraded from a standard Φ150 mm screw to a Φ180 mm screw, increasing channel volume and eliminating the "fluffy material choking" problem common with standard single-screw machines.

3. Large-Area Dual-Column Continuous Screen Changer — No Strand Breakage During Screen Change

Because PP's high flowability demands strand pelletizing, the line cannot tolerate the pressure interruption that a normal screen changer causes during swap-over. The dual-column filter keeps one column online while the other is changed, ensuring continuous melt flow, stable pressure, and zero strand breakage.

Combined with the single-plate dual-position unit upstream (80–120 mesh, configured to the customer's clean in-house scrap), this two-stage filtration delivers pellet purity high enough for direct reuse in PP yarn spinning.

4. Water-Flow Strand Pelletizing — Automatic Strand Traction

Traditional strand lines stop when a strand breaks because an operator must manually re-thread the die. The water-flow system uses guided water currents to automatically pull strands into the pelletizer. If a strand breaks, it self-recovers. This dramatically reduces manual intervention.
Final pellet specification: 3 × 3 mm cylindrical pellets, uniform and ready for re-extrusion.
