▏PVC Plastic Pellet Granulation Extrusion Line: High-Efficiency Production for Consistent Quality

Introduction to the PVC Plastic Pellet Granulation Extrusion Line

The PVC Plastic Pellet Granulation Extrusion Line is an advanced industrial system designed to transform raw PVC compounds into uniform, high-performance pellets for diverse manufacturing applications. Combining precision extrusion, granulation, and cooling technologies, this line ensures optimal material consistency, energy efficiency, and scalability for producers of pipes, profiles, cables, and other PVC-based products. With a focus on automation and process control, it meets the demands of large-scale production while adhering to global quality standards.

Core Components and Operational Workflow

Twin-Screw Extruder System

The heart of the line features a high-torque twin-screw extruder with segmented temperature zones (120°C–200°C), ensuring thorough PVC material plastication. Its modular screw design allows customization for different formulations (rigid/flexible PVC), while a vacuum degassing chamber removes volatiles, guaranteeing pellet purity.

Strand Pelletizing and Cooling Unit

Extruded strands are precision-cut into pellets via a rotary cutter with adjustable blade speed (0–3,000 RPM). The integrated water-ring cooling system rapidly reduces pellet temperature to 25°C–35°C, minimizing thermal stress and ensuring dimensional stability (tolerance ±0.2 mm).

Technical Specifications and Performance Metrics

Output Capacity: 500–2,500 kg/h (depending on model)
Pellet Size: 2–5 mm diameter, customizable
Motor Power: 55–160 kW, IE4 energy-efficient drive
Control System: Siemens PLC with HMI touchscreen for real-time monitoring
Energy Consumption: ≤0.25 kWh/kg (optimized heat exchange)

Competitive Advantages of the Extrusion Line

Precision and Consistency

The line achieves ≤1% pellet size variation through closed-loop feedback control, critical for downstream processes like injection molding. Anti-static vibrating screens classify pellets into A/B grades, reducing material waste.

Energy-Saving Innovations

A heat recovery unit captures 40% of residual thermal energy from cooling water, redirecting it to preheat raw materials. Combined with servo-driven motors, this reduces overall energy costs by up to 30% versus conventional systems.

Applications Across Industries

The PVC Plastic Pellet Granulation Extrusion Line serves sectors requiring rigorously standardized PVC feedstock:

Construction: Pellets for window profiles, pipes, and fittings
Electronics: Insulation-grade pellets for cable sheathing
Automotive: High-impact PVC pellets for interior components
Packaging: Food-safe transparent pellets for blister packs

Quality Assurance and Smart Features

Automated Quality Control

In-line sensors monitor pellet density (1.3–1.45 g/cm³), moisture content (≤0.3%), and melt flow index (MFI). Non-conforming pellets are automatically diverted to a recycling hopper, ensuring 99.9% product compliance.

Industry 4.0 Integration

The system supports OPC-UA protocol for integration with MES/ERP systems. Remote diagnostics via IoT modules enable predictive maintenance, minimizing downtime.

Environmental Compliance and Safety

The line features fume extraction systems with HEPA filtration, ensuring workplace air quality meets OSHA standards. All electrical components are ATEX-certified for explosive atmosphere operation.

▏Product Introduction

PVC Plastic Pellet Granulation Extrusion Granulators Production Line is an efficient plastic processing equipment, mainly used to process PVC and other plastic raw materials into granular products. The following is a detailed introduction of the production line:

1

Production line composition

PVC Plastic Pellet Granulation Extrusion Granulators Production Line is mainly composed of the following parts:

1. Raw material preparation system: including raw material storage, drying, mixing and other equipment, used to pre-treat raw materials such as PVC to ensure the drying and uniformity of raw materials.

2. Feeding system: The precision feeding device is used to evenly and quantitatively feed the pre-treated raw materials into the extruder.

3. Extrusion system: The core equipment is a conical twin screw extruder, which ensures that the raw materials are fully mixed and plasticized during the extrusion process through the screw form of low shear and high mixing.

4. Die surface heating system: The method of die surface heating is used to cut the extrusion plastic melt into particles. The die head is specially treated to ensure that the particle appearance is smooth and full, and the size is uniform.

5. Air delivery system: The fan is used to send the cut particles into the subsequent treatment equipment, such as cyclone separator, storage bin, etc. The air delivery system is made of stainless steel to ensure that particles are not contaminated during transportation.

6. Control system: The entire production line is equipped with advanced control system to achieve automated production. The control system includes temperature control system, drive system and interlock control system to ensure the stability and safety of the production process.

The production process

The production process of PVC Plastic Pellet Granulation Extrusion Granulators Production Line is roughly as follows:

1. After the raw materials are mixed with auxiliaries, they are fed to the extruder through the conveying system.

2. After the raw material is fully mixed and plasticized in the extruder, it is extruded into a molten body.

3. The melt is cut into particles by the die surface heating system.

4. The cut particles are sent to the cyclone separator through the air delivery system for separation.

5. The separated particles go into the storage bin for storage, and finally the finished product packaging.
