How to separate aluminum from plastic


There are a lot of waste aluminum-plastic composite materials in the market, so the separation of aluminum-plastic has become a hot spot of investment. However, the traditional separation method of chemical method has been eliminated due to its high cost, cumbersome process, pollution to the environment and harm to human beings, and now it mainly USES the method of physical separation to separate aluminum from plastic.

With the rapid development of modern industrial technology, the technology and products with each passing day, more and more aluminum products has been widely used in people’s life in various fields, such as food factory, cigarette factories, pharmaceutical factory, modern decoration materials, chemical industry and so on product packaging), has provided people with convenient, at the same time also brought a lot of disadvantage. Its bits and pieces and castoff (waste soft packaging bag, capsule board, tooth plaster, etc.) not only all over the place, and into every corner of people’s lives. So much, not only pollute the environment and caused a great waste of resources.

The aluminum in these aluminum-plastic composites is extremely pure and expensive, and it would be very economical to separate the aluminum from the plastic. It is based on this situation that WANROOETECH company produces aluminum plastic separation equipment. Aluminum plastic separation equipment using a completely dry physical separation method separated aluminum from the plastic, to achieve the recovery and reuse of resources.

The process of separating aluminum from plastics by the aluminum plastic separation equipment is as follows:
1. Crushing
This step is the starting point of the aluminum-plastic separation process. The purpose is to crush the aluminum-plastic composite material into small pieces or powder.By using a crusher, the material is broken into smaller particles, which helps in easier separation in subsequent steps.The particle size of crushing can be adjusted according to specific needs and equipment capabilities.

2. Screening
The purpose of the screening step is to separate the particle size of the crushed materials to ensure uniform size of the materials.Using screening equipment, particles of different sizes can be separated, making the subsequent sorting process more accurate and efficient.Through screening, particles that are too large or too small can be removed and materials suitable for sorting can be retained.

3. Electrostatic sorting
Electrostatic sorting is a method of separating aluminum and plastic based on the difference in conductivity.In an electrostatic separator, materials pass through charged electrodes. Aluminum is attracted to one collection device due to its good conductivity, while plastic is attracted to another collection device due to its poor conductivity.In this way, a preliminary separation of aluminum and plastic is achieved.

4. Gravity sorting or air flow sorting
These steps are performed to further improve the separation effect.Gravity sorting utilizes the different settling speeds and buoyancy differences of materials under the action of gravity to achieve separation through equipment such as vibrating screens and chutes.Airflow sorting uses the difference in flight speed of materials in the airflow to separate aluminum and plastic through the action of wind.
