HDPE And PP Rigid Plastic Shredding Recycling Line

Let’s talk plastic! High-density polyethylene (HDPE) and polypropylene (PP) are incredibly versatile materials used in countless products. However, their durability and bulk also mean they pose significant disposal challenges, contributing to landfill overflow and resource depletion. As the world increasingly seeks sustainable solutions, effectively recycling these plastics is more crucial than ever. That’s why we’re excited to introduce a powerful solution: our state-of-the-art HDPE and PP Rigid Plastic Shredding Recycling Line.

Why Choose Our Recycling Line?

• 🌎 Environmental Stewardship: Significantly reduce landfill burden, conserve natural resources (like petroleum used for virgin plastic), and lower the carbon footprint associated with plastic production and disposal.
• 💰 Economic Advantage: Create high-quality recycled pellets that offer a cost-effective alternative to virgin materials for manufacturers. Turn plastic waste, often seen as a liability, into a valuable commodity.
• ⚙️ Operational Efficiency: Our streamlined process, from shredding to pelletizing, is designed for high throughput and reliability, minimizing downtime and maximizing your output.
• ✨ Quality Output: Sophisticated cleaning and processing steps ensure the final pellets are clean and consistent, suitable for a wide range of manufacturing applications.

This innovative system is smartly engineered to take bulky, discarded HDPE and PP rigid plastics (think crates, pipes, drums, bottles) and shred them into manageable pieces. A conveyor belt then whisks these pieces away to an intermediate shredder, grinding them down even further into uniform flakes. Overcoming common recycling hurdles like contamination is key; that’s why our specialized cleaning system diligently removes impurities. A thorough drying system follows, ensuring the plastic is perfectly prepped for its next life. Finally, our high-performance pelletizer transforms this clean, processed material into high-quality, reusable plastic pellets – ready to fuel the circular economy and become brand new products!

Key Technical Specs & Consumption

Flexible Capacity Options: We understand different operations have different needs. That’s why we offer capacities ranging from 500 kg/hr up to a robust 2000 kg/hr.

Meticulous Processing for Quality: Our multi-stage system includes smart grading, powerful size reduction (crushing), and intensive washing stages. This ensures the removal of contaminants like dirt, labels, and non-target materials, guaranteeing clean, high-quality reusable plastic flakes.

A Closer Look: How the Components Work Together

Our recycling lines are modular and can be tailored to your specific input materials and quality requirements. A typical configuration might include these key pieces of equipment, each playing a vital role:

Belt Conveyor (Material Feed-In)

• Ensures a steady, controlled flow of bulky plastic waste into the system.
• Customizable length, width, and speed to match your operational needs.

Single-Shaft Shredder

• The powerhouse for initial size reduction, easily handling large, tough items.
• Generous cutting chamber (32% more space) and integrated hydraulic ram tackle challenging materials efficiently.
• Faster ram movement increases throughput, processing more material in less time.
• Compact footprint compared to traditional horizontal-ram designs.
• Enclosed cutting chamber enhances safety and prevents material leakage.

Belt Conveyor (Material Feed-Out)

• Reliably transfers shredded material to the next stage.
• Often features an “L-type” design for efficient connection to screening equipment like trommels.
• Equipped with essential pull-switch safety mechanisms along the conveyor length.

Crusher (Granulator)

• Provides secondary size reduction, turning shredded pieces into smaller, uniform flakes ideal for washing.
• Optimized rotor and chamber designs maximize output while minimizing energy consumption.
• Ideal rotor blade setup (“V-cut” or similar) efficiently processes rigid materials.
• Precise knife clearances ensure consistent particle size and reduce noise and fines generation.

Screw Loader

• Efficiently transports the plastic flakes, often while adding water to begin the washing process.
• Built with durable SUS304 stainless steel for corrosion resistance in wet environments.

Floating Tank (Float-Sink Tank)

• A critical step for purification: Uses water density to separate target plastics (HDPE/PP typically float) from heavier contaminants (like PVC, PET, metals, glass, dirt) which sink.
• Rotating paddles help submerge materials and move floating plastics forward while sinkable contaminants are removed from the bottom.
• Equipped with automatic water level control for consistent performance.

Friction Washer

• Provides intensive cleaning through high-speed scrubbing action.
• The high-speed rotor (mild steel) throws plastic flakes against a perforated stainless steel screen, dislodging dirt and residues.
• Water spray nozzles continuously clean the screen, preventing clogging.
• Integrated water pump recirculates water for efficient washing. (Hot washing option available for stubborn contaminants).

Dewatering Machine (Centrifugal Dryer)

• Removes excess surface water after washing – a crucial step before thermal drying or pelletizing.
• Uses high-speed centrifugal force to spin water off the plastic flakes effectively.
• High humidity removal efficiency (typically ≥ 98%) reduces the load on the thermal dryer, saving energy.
• Durable construction with stainless steel housing and a reinforced screen ensures longevity and performance.

Pipe Drying System (Thermal Dryer)

• Further reduces moisture content using heated air, ensuring flakes are dry enough for pelletizing or sale.
• Hot air conveys the flakes through stainless steel pipes, evaporating remaining moisture.
• A cyclone separator efficiently collects the dried flakes while allowing moist air to exit.

Packaging System with Dust Remover

• The final stage: Dried flakes are collected in a storage silo, often equipped with a dust removal system for a cleaner product and working environment.
• Ready for bagging (e.g., into bulk bags) or direct feeding into a pelletizer.

Applications: Giving Plastic a Second Life

The high-quality HDPE and PP pellets produced by our recycling line are incredibly versatile and sought after for manufacturing a wide array of new products, including:

• Pipes: Drainage pipes, corrugated pipes, conduits.
• Containers: Crates, bins, pallets, drums, storage containers.
• Automotive Parts: Bumpers, interior trims, battery casings.
• Household Goods: Buckets, bowls, outdoor furniture, toys.
• Construction Materials: Plastic lumber, decking components, insulation materials.

Choosing our recycling line is an investment in sustainability and efficiency. It’s a robust, eco-friendly system designed to transform challenging plastic waste into valuable resources, helping you reduce operational costs and contribute positively to the environment. Good for the planet, great for your business!
