What are the processing steps in an aluminum-plastic recycling plant?

An aluminum-plastic recycling plant is a specialized facility for processing waste aluminum-plastic composite 

materials. It does not use chemical methods, but rather employs crushing, grinding, and physical separation

 technologies to efficiently separate aluminum powder and plastic powder.

Uses of the final products (aluminum powder and plastic powder):

The separated materials can be reused. Aluminum can be used in metallurgical and industrial applications,

 while plastic can be used in manufacturing or as an additive.

Working principle and process:

A typical recycling production line includes the following steps:

1- Feeding

Waste aluminum-plastic materials (such as pharmaceutical blister packaging or composite panels) are fed 

into the machine via a conveyor belt.

2- Crushing

The material is crushed into fine fragments by a crusher, exposing the aluminum and plastic layers.

3- Grinding and pulverizing

A high-speed grinder further grinds the material into fine particles, ensuring complete separation of aluminum

 and plastic.

4- Airflow separation (gravity separator):

The gravity separator has two outlets (one for aluminum and one for plastic), utilizing density differences to 

separate the lighter plastic particles 

from the heavier aluminum powder.

5. Electrostatic Separation (High-Voltage Electrostatic Separator):

When particles pass through an electrostatic field, conductive materials (such as metals) discharge rapidly and settle,

 while non-conductive materials (such as plastics, resins, or rubbers) retain their charge and are adsorbed onto the 

collection plate. Electrostatic separators utilize the difference in conductivity between aluminum and plastics 

to improve purity.

Dust Removal

Integrated dust removal systems prevent particulate matter emissions, ensuring a clean and environmentally

 friendly operating environment.

Advantages of Aluminum-Plastic Recycling Machines:

High Separation Efficiency

Aluminum recovery rates can reach 98% or higher.

Environmentally Friendly

No combustion or chemical treatment is required, avoiding toxic emissions.

Economical Benefits

Both recycled aluminum and plastics have market value, making recycling profitable.

Versatility

Can process various aluminum-plastic composite materials, including pharmaceutical packaging, aluminum foil laminates

 and decorative panels.

Automation and Safety

Equipped with an advanced control system, it is easy to operate, has a stable design, and requires minimal manual labor.
