The 500–6,000 kg/h pet plastic recycling granulator machine is an industrial extrusion and granulation system designed to convert clean,dried pet bottle flakes into uniform recycled pet pellets.It is suitable for plastic recycling plants that require stable output,efficient operation,and flexible production capacity.
The plastic granulator machine is commonly integrated after a pet bottle washing line and is engineered for continuous processing of post-consumer pet flakes.Depending on the required pellet quality,the machine can be configured with advanced filtration,vacuum degassing,melt homogenization,and automatic pelletizing equipment.
Product Overview
These pet plastic granulator machines processes pet flakes generated from waste beverage bottles,mineral water bottles,packaging materials,and other compatible pet products.The flakes are melted,filtered,extruded,cooled,and cut into consistent pellets for use in the production of polyester fiber,strapping,sheets,injection-molded products,and other recycled plastic applications.
With capacity options from 500 to 6,000 kg/h,these plastic granulators can be configured for small,medium,and large-scale recycling operations.
Main Features
1. Wide Capacity Range
- Production capacity: 500–6,000 kg/h
- Suitable for different plant sizes and investment requirements
- Modular equipment configuration for future capacity expansion
- Output capacity can be adjusted according to pet flake quality,moisture content,and product requirements
2. Designed for Pet Bottle Recycling
The granulator for plastic recycling is specifically configured for processing pet flakes from recycled bottles.It can be connected directly to a pet bottle washing and drying line to create a complete bottle-to-pellet recycling solution.
Typical feedstock includes:
- Clear pet bottle flakes
- Colored pet bottle flakes
- Washed post-consumer pet flakes
- Post-industrial pet scrap
- Pet sheet and packaging waste,subject to material compatibility
3. Efficient Extrusion System
The extruder melts and homogenizes pet material under controlled temperature conditions.A specially designed screw configuration helps achieve stable conveying,thorough melting,and uniform melt quality.
The extrusion system can be equipped with:
- High-strength screw and barrel components
- Temperature control zones
- Melt pressure monitoring
- Automatic feeding system
- Vacuum degassing unit
- Wear-resistant parts for long service life
4. Advanced Melt Filtration
An efficient filtration system removes remaining impurities from the molten pet before pelletizing.Depending on the contamination level and final product requirements,the pet granulator line may use:
- Screen changers
- Continuous melt filters
- Automatic backflush filtration systems
- Multi-stage filtration configurations
Effective filtration helps protect downstream equipment and improves the appearance and consistency of the recycled pellets.
5. Vacuum Degassing
The vacuum degassing system removes moisture,air,and volatile substances from the molten pet.This is particularly important because pet is highly sensitive to moisture.Proper drying and degassing help reduce:
- Hydrolysis during processing
- Melt viscosity loss
- Bubbles and voids
- Black spots and processing defects
- Inconsistent pellet quality
6. Uniform Pelletizing
The pet pelletizing line can be configured with water-ring,strand,or underwater pelletizing technology depending on capacity and product requirements.
The pelletizing section produces consistent,easy-to-handle recycled pet pellets with controlled size and shape.Uniform pellets are suitable for further processing,storage,transportation,and automated feeding.
7. Plc Automatic Control
The control system provides centralized monitoring of key operating parameters,including:
- Extruder temperature
- Melt pressure
- Screw speed
- Feeding rate
- Pelletizer speed
- Cooling water temperature
- Motor load
- Vacuum pressure
PLC control helps improve operating stability,reduce manual adjustment,and support efficient production management.
8. Energy-Efficient Operation
The pet granulating machine is designed to reduce unnecessary energy consumption through optimized heating,motor control,feeding,and cooling systems.Optional energy-saving components may include:
- Variable-frequency drives
- High-efficiency motors
- Insulated heating zones
- Automatic temperature control
- Efficient cooling-water circulation
- Optimized extruder screw design
Actual energy consumption depends on the capacity,raw material condition,moisture content,product quality,and selected configuration.
Advantages for Recycling Plants
- Converts waste pet bottles into reusable recycled raw material
- Supports capacities from 500 to 6,000 kg/h
- Improves material value compared with selling loose flakes
- Provides stable and uniform pellet quality
- Reduces dependence on virgin PET resin
- Suitable for continuous industrial production
- Configurable for different feedstock quality levels
- Integrates with complete PET bottle washing lines
- Simplifies storage,transport,and automatic material feeding
- Can be customized according to plant layout and end-product requirements
Recommended End Uses for Recycled Pet Pellets
The produced pet pellets can be used in a range of downstream applications,including:
- Polyester staple fiber
- Filament yarn
- Pet strapping band
- Thermoforming sheet
- Packaging sheet
- Injection-molded components
- Non-food containers and industrial products
- Recycled plastic compounds
For demanding applications,additional processing controls and quality testing may be required.Food-contact or bottle-to-bottle applications typically require specialized decontamination,solid-state polycondensation,and regulatory compliance systems.
Customization Options
The pet plastic pelletizing machine can be customized according to:
- Required output capacity
- Pet flake moisture content
- Contamination level
- Flake size and bulk density
- Clear or colored PET material
- Required intrinsic viscosity retention
- Pellet size and shape
- Available factory space
- Automation level
- Final product application
- Local electrical and installation requirements
Conclusion
The 500–6,000 kg/h pet pellets maker provides an efficient solution for converting washed pet bottle flakes into high-quality recycled pellets.With configurable extrusion,degassing,filtration,cooling,and pelletizing systems,it can meet the needs of different plastic recycling plants and production scales.
The pet recycling pelletizing machine is suitable for companies seeking to increase the value of waste pet,improve recycling efficiency,and produce consistent recycled material for fiber,strapping,sheet,injection molding,and other applications.
