Tarpaulins and waterproof fabrics – commonly used in truck covers, outdoor tents, billboards, and protective gear—are engineering marvels designed to withstand extreme weather. However, their high tensile strength, heavy thickness, and frequent multi-material composition make them a nightmare for traditional recycling systems.

To tackle these robust materials without degrading the polymer quality, Purui Machinery rely on a specialized integrated shredding + pelletizing machine. This plastic recycling system streamlocks the process, turning tough industrial textile waste into uniform, high-value resin pellets.

Step 1: Shredding & Size Reduction

Because waterproof fabrics are heavily reinforced to resist tearing, standard granulators will quickly jam or overheat.

• High-Torque Single-Shaft Shredder: The recycling system begins with a low-speed, high-torque shredder. It effortlessly shears through thick rolls of tarpaulin, canvas, and coated fabrics.
• Smart Feeding: Equipped with a hydraulic pusher, the shredder forces the bulky fabric against the cutting rotor, ensuring a consistent output of uniform shreds without overloading the machine.

Step 2: Advanced Pelletizing with Specialized Extrusion

Once shredded, the material is continuously fed into the plastic pelletizing line. For coated fabrics like PP PE or polyurethane (PU) on polyester, precision is key:

• Cutter Compactor Technology: The shredded flakes enter a compactor where friction pre-heats and densifies the fluffy fabric. This process also drives off surface moisture, which is common in outdoor tarpaulins.
• Targeted Degassing & Filtration: Heavy coatings and inks release high amounts of volatiles during melting. The extruder utilizes multi-point vacuum degassing zones to strip away toxic gases and moisture. Simultaneously, a hydraulic non-stop screen changer filters out residual reinforcement fibers to ensure a pure melt.
• Pelletizing: Depending on the material base (PE or PP), a water-ring pelletizing system creates uniform, dust-free pellets ready for manufacturing.

Economic and Environmental Value:

By utilizing a closed-loop shredding and pelletizing line, factory scrap (post-industrial) and used covers (post-consumer) no longer end up in landfills. The resulting recycled pellets can be reintroduced into injection molding, compounding, or the production of new industrial covers, drastically lowering carbon footprints.

FAQ:

Q1: What happens to the internal fiber reinforcement during pelletizing?

A: The internal high-strength fibers (like polyester mesh) are melted and mixed if chemically compatible, or filtered out using our high-pressure hydraulic non-stop screen changer. This ensures that the final pellets are smooth and free of unmelted fibrous contamination.

Q2: Is a washing line required before the shredding and pelletizing process?

A: For post-industrial scrap (factory edge trims and clean waste rolls), no washing is needed – the shredder + pelletizing line can process it directly. For post-consumer tarpaulins (used truck covers caked in mud or road grime), we highly recommend running the shredded flakes through a washing segment before pelletizing to protect the filters and improve pellet purity.

Q3: Why is plastic recycling important for my business and the environment?

A: From a business perspective, recycling plastic can turn waste into a valuable resource, reduce operational costs, and create a new revenue stream. Environmentally, it helps reduce landfill waste, conserve fossil fuels used in the production of new plastic, and lower greenhouse gas emissions.
