Factors such as the type and purity of waste plastic, the efficiency of sorting and cleaning, the temperature and shear control during extrusion, and the design of the extruder all have a significant impact on the final product quality. Therefore, developing a simple, convenient, maqosa, vakabula kaukauwa, environmentally friendly, and economically viable granulation process has become the focus of research and development in the plastic recycling industry.

1.1 Key Characteristics of Recycled Plastic Granules

The performance of recycled plastic granules is closely related to the type of waste plastic, the degree of contamination, and the granulation process. In general, high-quality recycled granules should possess the following characteristics:

Uniform Particle Size: Consistent particle size ensures stable feeding during subsequent processing (such as injection molding and extrusion), improving the uniformity and quality of the final product. The particle size of recycled granules is typically between 2mm and 5mm, depending on the application requirements.
Low Contamination: Contaminants such as dirt, dust, metal fragments, paper, and other non-plastic materials can significantly affect the performance of recycled granules and the final product. Therefore, effective sorting and cleaning of waste plastic are essential to ensure low contamination levels.
Good Plasticity and Processability: Recycled granules should have good melting properties and flowability, allowing for easy processing into new products without affecting the processing efficiency or product quality. This requires precise control of the temperature and shear rate during the granulation process to avoid excessive degradation of the plastic molecular structure.
Stable Mechanical Properties: The tensile strength, elongation at break, impact strength, and other mechanical properties of recycled granules should be as close as possible to those of virgin materials, ensuring that the final recycled products meet the required performance standards.
Low Moisture Content: High moisture content in recycled granules can lead to defects such as bubbles and cracks in the final product during processing. Therefore, drying steps are often required during the granulation process to reduce the moisture content to an acceptable level (typically below 0.5%).

1.2 Common Types of Waste Plastics for Granulation

Almost all types of thermoplastic plastics can be recycled and granulated, while thermosetting plastics (which cannot be melted and reprocessed) are not suitable for recycling granulation. The most common types of waste plastics used in recycling granulation include:

PP (Polipropilini): A widely used thermoplastic with good chemical resistance, mechanical properties, and processability. Common waste PP includes plastic buckets, koniteina, caps, and production scraps. Recycled PP granules are often used to produce plastic pipes, auto parts, and packaging materials.
PE (Polietileni): Divided into LDPE (Na polietileni lailai) and HDPE (High-Density Polyethylene). LDPE is commonly used in plastic films, taga, and bottles, while HDPE is used in barrels, paipo, and containers. Recycled PE granules are suitable for producing plastic films, paipo, and injection-molded products.
MANUMANU (Tereftalate ni polietileni): A transparent, rigid plastic commonly used in beverage bottles, food packaging, and fiber products. Recycled PET granules are widely used in the production of polyester fibers, plastic bottles, and packaging materials.
PS (Polisitireni): Available in rigid (such as foam cups, food containers, and plastic toys) and foam (EPS, expanded polystyrene) forms. Recycled PS granules can be used to produce plastic toys, decorative materials, and foam products.
ABS (Akirilonitirile Butadeini Sitireni): A high-performance plastic with good impact strength, rigidity, and heat resistance. Common waste ABS includes plastic shells of electronic products, auto parts, and toys. Recycled ABS granules are used to produce electronic product shells, auto parts, and injection-molded components.

Zhuoyue’s recycling granulation production lines are designed to handle all the above-mentioned waste plastics, with customized equipment configurations to meet the specific processing requirements of different plastic types.

2. The Waste Plastic Recycling Granulation Process

The waste plastic recycling granulation process typically consists of several key steps: waste plastic collection and sorting, cleaning, crushing, mamaca, extrusion granulation, vakacegu, and cutting. Each step plays a crucial role in ensuring the quality of the final recycled granules. The specific process parameters may vary depending on the type of waste plastic, the degree of contamination, and the desired quality of the recycled granules.

2.1 Collection and Sorting

The first step in the recycling granulation process is the collection and sorting of waste plastics. Waste plastics are collected from various sources, including households, industries, commercial establishments, and production lines. Due to the wide variety of waste plastics and the presence of contaminants, sorting is essential to ensure the quality of the recycled granules.

Once the strands are cooled and solidified, they are cut into uniform granules using a pelletizer. The pelletizer is typically installed at the exit of the cooling system and can be adjusted to control the length of the granules (usually between 2mm and 5mm). Common types of pelletizers include strand pelletizers, water ring pelletizers, and underwater pelletizers. Strand pelletizers are the most widely used type for waste plastic recycling granulation, as they are simple in structure, easy to operate, and suitable for most types of plastics.

3.1 Twin-screw Extruders for Recycling Granulation

Twin-screw extruders are widely used in the recycling granulation of engineering plastics and plastics with high contamination levels, such as ABS, PS, kei na PET. They consist of two parallel screws that rotate in the same direction (co-rotating) or opposite directions (counter-rotating) within a barrel. Co-rotating twin-screw extruders are more commonly used in plastic recycling due to their superior mixing and conveying capabilities.

3.1.1 Key Advantages of Twin-screw Extruders

Easy Material Feeding: Twin-screw extruders have a strong conveying capacity, which allows for easy feeding of crushed plastic pieces, kevaka mada ga era sega ni tudei na kedra irairai se tiko kina e dua na iwiliwili ni veivakacacani ..

Na tiki ni meshing ni sikivu e vakarautaka na veiwaki vinaka ., and the self-cleaning function of the venting section ensures that the material can achieve complete surface renewal, allowing for efficient removal of volatile substances. This helps to improve the quality of the recycled granules by reducing the number of bubbles and defects.
Superior Mixing and Plasticizing Effect: The co-rotating twin-screw extruders have strong shear and mixing capabilities, which can effectively homogenize the molten plastic, disperse contaminants, and mix additives (such as stabilizers, antioxidants, and colorants) uniformly. This ensures that the recycled granules have consistent properties and good processability.
Low Specific Power Consumption: Despite their high performance, twin-screw extruders have low specific power consumption (power consumption per unit output), cakava me ra kaukauwa-vakayagataki vakalevu cake ni vakatauvatani kei na dua-sikirini extruders me baleta na kerekere eso ..

MANUMANU: PET is highly sensitive to moisture and heat, and requires precise temperature control and short residence time. Twin-screw extruders with good venting and temperature control capabilities are suitable for PET recycling granulation.
Engineering Plastics: Other engineering plastics such as PC (Polikabonati), PA (Poliamidi), and POM (Polyoxymethylene) can also be recycled using twin-screw extruders, thanks to their superior mixing and plasticizing capabilities.

3.2 Single-screw Extruders for Recycling Granulation

Single-screw extruders are simpler in structure, lower in cost, and easier to maintain compared to twin-screw extruders. They consist of a single screw that rotates within a barrel, conveying and melting the material through friction and shear between the screw and the barrel. Single-screw extruders are widely used in the recycling granulation of general-purpose plastics such as PP, PE, and LDPE.

3.2.1 Key Advantages of Single-screw Extruders

Short Screw Length and Residence Time: Single-screw extruders typically have a shorter screw length compared to twin-screw extruders, resulting in shorter material residence time. Oqo e vukea me kua ni vakacacani na palasitika ena katakata ., especially for soft plastics such as PE and LDPE, which have lower melting points and are prone to degradation.
Cost-Effective: Waste plastic recycling often involves materials with high levels of contaminants, which can cause significant wear and tear on the extruder screw and barrel. Single-screw extruders are simpler in structure and use less expensive materials, making them more cost-effective to replace and maintain compared to twin-screw extruders. This is particularly important for small and medium-sized recycling enterprises with limited budgets.
Suitable for Soft Plastics: The material conveying efficiency of single-screw extruders depends on the friction performance of the solid material and the viscosity of the melt. Soft plastics such as PP, PE, and LDPE have good friction performance and low melt viscosity, making them ideal for processing with single-screw extruders. These plastics can be conveyed and melted efficiently, ensuring good granule quality.
Simple Operation and Maintenance: Single-screw extruders have a simple structure, with fewer moving parts, making them easy to operate and maintain. This reduces the need for skilled operators and lowers maintenance costs, which is beneficial for small-scale recycling operations.

3.2.2 Suitable Applications for Single-screw Extruders

Single-screw extruders are particularly suitable for the recycling granulation of the following plastics:

PP (Polipropilini): PP is a soft plastic with good friction performance and processability, making it ideal for processing with single-screw extruders. Recycled PP granules produced using single-screw extruders have good mechanical properties and can be used in a wide range of applications.
PE (Polietileni): Both LDPE and HDPE are suitable for processing with single-screw extruders. LDPE, vakabibi, is a soft plastic with low melt viscosity, which can be conveyed and melted efficiently by single-screw extruders. Recycled PE granules are widely used in the production of plastic films and pipes.

Thoroughly clean the waste plastics to remove oil, waiwai, kei na vo ni kakana ., which can affect the mixing and plasticizing effect.

5.2 Optimal Drying

Ensure that the crushed plastic pieces are properly dried to reduce the moisture content to below 0.5%. For moisture-sensitive plastics such as PET, use high-temperature drying (120-160°C) for a sufficient period to ensure complete moisture removal. This helps to avoid bubbles and defects in the recycled granules.

5.3 Precise Process Parameter Control

Adjust the extruder parameters (such as temperature, totolo ni sikivu, and extrusion pressure) according to the type of waste plastic. Follow the recommended parameter settings provided by Zhuoyue, and make adjustments based on the actual material properties and granule quality. Avoid excessively high temperatures or shear rates, which can cause plastic degradation.

5.4 Regular Maintenance

Regularly inspect and maintain the extruder to ensure its normal operation. Clean the screws and barrels regularly to remove any accumulated material or contaminants. Check the wear of the screws and barrels, and replace them when necessary. Lubricate the moving parts regularly to reduce friction and extend the service life of the extruder.
