Product Description

One Machine. One Process. One Complete Plastic Recycling Solution.

Plastic manufacturers and recyclers are under increasing pressure to reduce waste, lower production costs, and improve sustainability. However, conventional recycling systems often require multiple independent machines, additional labor, and large factory space to process production scrap into reusable plastic pellets.


The Chenxing Shredder Extruder Recycling Pelletizing System integrates shredding, extrusion, filtration, degassing, pelletizing, drying, and conveying into one intelligent recycling platform.


This advanced 3-in-1 recycling solution eliminates traditional pre-crushing and material transfer steps, allowing plastic waste to be directly converted into high-quality recycled pellets with minimal labor and maximum efficiency.


Designed for in-house recycling and industrial plastic waste recovery, this system is widely used by plastic film manufacturers, woven bag producers, packaging factories, plastic recyclers, and compound manufacturers worldwide.

Why Manufacturers Need an Integrated Recycling Pelletizing System

Every plastic production facility generates valuable production scrap:

  • PE film edge trims

  • PP woven bag waste

  • Printed film scraps

  • Start-up purge lumps

  • Non-woven fabric waste

  • Defective products

  • Injection molding runners

  • Rigid plastic rejects


Traditional recycling methods require:

  1. Collection

  2. Crushing

  3. Material transport

  4. Storage

  5. Feeding

  6. Extrusion

  7. Pelletizing


This creates:

  • Higher labor costs

  • Additional factory space requirements

  • Increased energy consumption

  • Material contamination risks

  • Reduced production efficiency

The Chenxing integrated recycling pelletizing system solves these challenges by combining multiple processes into one continuous operation.


What Is a Shredder Extruder Recycling Pelletizing System?

A Shredder Extruder Recycling Pelletizing System is a highly integrated plastic recycling machine that combines:

Material Size Reduction

Shredding incoming plastic scrap.


Extrusion

Melting and homogenizing plastic materials.


Filtration

Removing contaminants and impurities.


Degassing

Eliminating moisture and volatile gases.


Pelletizing

Producing uniform recycled plastic pellets.


Drying & Conveying

Preparing pellets for storage, packaging, or reuse.

The entire process operates continuously with intelligent automation and minimal operator intervention.



Main Advantages

3-in-1 Integrated Design

Traditional recycling requires separate machines.

Our integrated system combines:

  • Shredder

  • Extruder

  • Pelletizer

into one compact production line.

Benefits include:

  • Reduced installation space

  • Lower investment cost

  • Less material handling

  • Simplified operation


Elimination of Pre-Crushing

Unlike traditional systems, many soft plastic materials can be directly fed into the machine without separate crushing operations.

Suitable for:

  • Film rolls

  • Woven bags

  • Jumbo bags

  • Raffia

  • Non-woven fabric

  • Plastic trims


Energy Savings

Integrated operation significantly reduces:

  • Material transfer energy

  • Handling costs

  • Motor load fluctuations

Energy savings can reach 15%–20% compared to conventional recycling lines.


Higher Production Efficiency

Continuous processing allows:

  • Stable throughput

  • Consistent pellet quality

  • Reduced downtime

  • Faster production cycles


Intelligent Automation

The system incorporates:

  • ABB inverter-controlled drives

  • Automatic feeding regulation

  • Intelligent process monitoring

  • Emergency protection systems

  • Optional Bluetooth remote monitoring



Working Principle

Step 1: Material Feeding

Plastic waste is fed into the integrated shredding chamber via conveyor.

Suitable materials include:

  • Plastic films

  • Woven bags

  • Non-woven fabrics

  • Purge lumps

  • Plastic containers

  • Foam plastics

  • Rigid plastics


Step 2: Shredding

Heavy-duty shredding rotors cut incoming material into uniform flakes.

Benefits:

  • Improved feeding consistency

  • Reduced material bridging

  • Stable extrusion performance


Step 3: Extrusion & Plasticization

The shredded material enters the extruder where it is:

  • Heated

  • Melted

  • Homogenized

  • Compressed

The optimized screw design ensures stable melt pressure and excellent plasticization quality.


Step 4: Filtration

The melt passes through advanced filtration systems.

Available options include:

Single Plate Screen Changer

Suitable for relatively clean materials.


Double-Piston Screen Changer

Continuous operation with minimal downtime.


Self-Cleaning Filter (SCF)

Removes contaminants up to 5%.

Suitable for:

  • Paper contamination

  • Aluminum residues

  • Rubber particles

  • Labels


Step 5: Degassing

Vacuum degassing removes:

  • Moisture

  • Printing solvents

  • Volatile gases

  • Organic residues

This improves pellet quality and reduces defects.


Step 6: Pelletizing

The molten polymer is cut into uniform pellets using:

Water-Ring Pelletizer

Produces highly uniform granules.


Die-Face Pelletizer

Suitable for multiple plastic materials.

Features include:

  • Self-adjusting cutter

  • Automatic blade pressure control

  • Automatic RPM adjustment


Step 7: Drying & Collection

Finished pellets pass through:

  • Vibrating screens

  • Horizontal centrifugal dryers

Resulting in:

  • Low moisture content

  • Clean pellets

  • Improved storage performance
