Type A Plastic Recycled Pelletizer
Plastic Waste Recycling Machine for Multi-Material Plastic Recycling
Green Earth's Type A plastic waste recycling machine is an industrial recycling and pelletizing system designed to convert suitable thermoplastic waste into reusable plastic pellets. The line can be configured for materials including PP, PE, PS and ABS according to the characteristics of the incoming waste and the required recycled pellet specifications.
The complete system integrates material sorting, crushing, washing, dehydration, drying, extrusion, melt filtration, pelletizing, cooling, screening and packaging. Its modular configuration allows plastic processors and recycling companies to select suitable equipment according to material type, contamination level, processing capacity and downstream application.
By recovering production scrap and suitable post-consumer plastic waste, the system helps manufacturers convert waste polymers into reusable feedstock for injection molding, extrusion and other plastic processing applications.
Materials Suitable for Recycling
Type A is designed for a range of thermoplastic waste streams rather than a single dedicated polymer. The equipment configuration can be adjusted according to material properties and processing requirements.
| Material | Typical Recyclable Feedstock |
|---|---|
| PP | Containers, production scrap and rigid plastic products |
| PE | Plastic film, containers and production waste |
| PS | Selected rigid PS products and industrial scrap |
| ABS | Selected industrial plastic components and production scrap |
Material suitability depends on polymer type, moisture, contamination, additives, melt flow characteristics and the required quality of the recycled pellets.
For projects focused specifically on polystyrene processing, Green Earth also provides a dedicated polystyrene pelletizing line for suitable PS recycling applications.
Plastic Waste Recycling Process
The production line uses a continuous processing configuration to prepare waste plastics for stable extrusion and pelletizing.
1. Sorting and Feeding
Waste plastics are sorted according to polymer type, size, color and contamination level. Manual sorting or an automatic sorting system can be selected according to the incoming material.
A controlled feeding system then transfers the sorted material into the preprocessing section.
2. Crushing and Size Reduction
A dedicated crusher reduces bulky plastic waste into smaller flakes or particles. Consistent particle size improves conveying, washing, drying and subsequent extrusion.
The crusher configuration can be selected according to the thickness, hardness and form of the incoming waste.
3. Washing and Contaminant Removal
The crushed plastic enters a cleaning system where surface dirt, labels, dust and other contaminants are removed.
Washing intensity and equipment configuration can be adjusted according to the contamination level of the feedstock.
4. Dehydration and Drying
After washing, centrifugal dehydration removes free water from the plastic flakes. A hot-air drying system then further reduces residual moisture before extrusion.
Effective moisture control helps improve melt stability and reduce processing problems during pelletizing.
5. Melting and Plasticizing
The dried plastic flakes are continuously fed into the extruder.
Controlled heating and screw shear gradually melt and homogenize the material. Depending on the polymer and required output, the system can use a single-screw or twin-screw extrusion configuration.
The extrusion system is designed to provide stable melt temperature and pressure throughout continuous production.
6. Melt Filtration
The molten polymer passes through a high-precision filtration system to remove remaining contaminants.
The filtration configuration can include:
- Hydraulic quick-change screen changer
- Automatic self-cleaning filter
- Fine filtration system
- Pressure monitoring
Continuous filtration helps reduce production interruptions and protects the downstream die and pelletizing system.
7. Pelletizing
After filtration, the molten plastic is extruded through a die plate and cut into uniform pellets.
Different pelletizing configurations can be selected according to polymer type and production requirements, including air-cooling, water-cooling and water-ring pelletizing systems.
8. Cooling and Screening
Freshly cut pellets are cooled and solidified before entering the screening system.
The vibrating screen separates oversized, undersized and defective particles from qualified recycled pellets. Rejected material can be collected and returned to the recycling process when appropriate.
9. Packaging
Qualified pellets are conveyed to an automatic packaging system.
The packaging configuration can support standard 25 kg bags or larger FIBC bulk bags according to transportation and storage requirements.
Core Equipment Configuration
The Type A system uses a modular equipment structure so that each processing stage can be configured according to the material and target output.
Raw Material Preparation System
The preprocessing section can include:
- Sorting equipment
- Plastic crusher
- High-pressure washing system
- Centrifugal dehydrator
- Hot-air dryer
- Material conveying system
The objective is to reduce particle size and remove contaminants and moisture before extrusion.
Extrusion and Melt Processing System
The extrusion section is the core of the recycling line. Single-screw or twin-screw extruders can be selected according to polymer characteristics, production capacity and required melt quality.
The system combines:
- Controlled heating
- Screw plasticization
- Melt homogenization
- Pressure control
- Melt filtration
- Optional vacuum degassing
Green Earth can also configure the recycling line with an industrial extrusion system according to the polymer, output requirements and downstream processing conditions.
Pelletizing and Cooling System
The pelletizing section converts the filtered polymer melt into reusable pellets.
Available configurations can include:
- Air-cooling pelletizing
- Water-cooling pelletizing
- Water-ring pelletizing
- Pellet cooling
- Dewatering
- Vibrating screening
- Finished pellet conveying
The selected configuration depends on the polymer's melt characteristics, pellet specifications and production requirements.
