How to Choose the Right Plastic Film Recycling System

Key factors to consider when selecting a plastic film system include material compatibility, production capacity, energy efficiency, installation, and maintenance requirements. Most importantly, choosing excellent shredding equipment for pre-treatment can make the pelletizing system even more efficient. Langye Environmental's recycling system stands out, and its detailed introduction is below.

Pretreatment: Lays the foundation for efficient film shredding

Shredding and cleaning systems are the core of the front-end process for plastic film recycling. High-quality pretreatment directly impacts the stability of the film recycling system and the quality of the output pellets. Pretreatment steps and key equipment include:

1. Shredding: Cuts bulk material into smaller, more uniform pieces. Film-type materials are opened to allow for effective cleaning and washing.

Langye Environmental Protection LYHS Series Pre-Crusher: A low-speed, high-torque, low-dust, and low-noise machine suitable for film, rigid plastics, and bulky materials.

Langye Environmental Protection LYH Series Single-Shaft Shredder: A small- to medium-sized shredder suitable for processing a variety of materials into uniform particle sizes.

2. Crushing: Further reduces particle size for consistent feed.

Langye Environmental Protection HG Series Crusher: A high-speed crusher suitable for processing a variety of materials, including plastics, rubber, fiber, cable, and more.

3. Cleaning and Drying: Essential for contaminated and impure materials. The pre-wash system efficiently removes most impurities such as silt, protecting subsequent equipment and significantly extending the service life of the crushing and cleaning systems.

The high-speed centrifugal cleaning system optimizes the rotation speed and blade impact force for different materials to achieve optimal cleaning results.

The drum in the cleaning tank features a high-pressure underwater cleaning design to maximize the removal of residual impurities. The claw-type uniform discharge ensures uniform discharge while controlling moisture content, providing a process foundation for the dehydration module.

The thin-film drying technology, which combines centrifugal dehydration, screw drying, and high-temperature hot air, strictly controls the moisture content of the finished product to less than 5%, meeting the requirements of high-quality granulation.

Choosing a Film Recycling System: Matching Material Requirements

Plastic pelletizing is a plastics processing process in which pre-crushed plastic is melted at high temperatures and reformed into uniform, stable, and standardized recycled plastic pellets, typically cylindrical or spherical.

The type of plastic material significantly influences the choice of pelletizer. Common plastics include:

Polyethylene (PE)

Polypropylene (PP)

Polyvinyl chloride (PVC)

Polystyrene (PS)

Technical plastics (ABS, nylon, etc.)

Each material has different melting points, viscosities, and handling requirements. Therefore, the selected pelletizer must be compatible with the plastic being processed.

Technical Parameters to Consider

When comparing different pelletizing systems, it is recommended to consider the following technical parameters:

• Production capacity

• Discharge diameter (customizable)

• Speed

• Temperature range

• Heating and cooling requirements

• Operational efficiency

• Energy savings

• Maintenance costs
