Plastic Sorting Machine

SG Plastic Sorting Machine, also called plastic color sorter, is designed for plastic and recycled plastic sorting. It is not only used to sort the shredded, granulated plastics and PET flakes but also to handle larger objects, such as PET bottles.

It quickly removes impurities from plastic mixtures and classifies plastics by type and color. For example, it can pick out blue PVC from light blue PTC materials.

  1. Remove Metal, Paper, Dust and other impurities from the plastic mixture;
  2. Separate opaque from transparent Plastics;
  3. Sorting Objects contain all types of plastic such as PVC, PET, HDPE, LDPE, and PP.

SG Plastic Color Sorter installs a 10” of the visualized touch screen. Meanwhile, all SG plastic sorting machines integrate 20 different kinds of sorting plans in order to suit various types of plastic.

Besides, this plastic sorting equipment integrates with an intelligent self-learning function that makes the operation quite simple and easy.

As a professional Plastic sorting machine manufacturer, Sortex Group has a complete and mature plastic optical sorting technology that ensures optimum performance, long service life.

Optical Sorting equipment is ideal for waste plastic recycling

SG Chute-Type Plastic Color Sorter, sometimes it is also called CCD Color Sorter by technical experts. It can sort out three color material one time.

It has a great feature – Chute. The Sorted Plastics must go through the chutes before entering the sorting cabinets.

Due to the limit of the channel’s width, it can only be used to plastic pellets and plastic flakes.

SG Chute Plastic Sorting Machine has a 1X ~ 12X different sorting capacity to match your processing demands at 98% sorting accuracy.

Chute-Type Plastic Sorting Machine

It adopts two individual sorting cabinets with the full-color sensor, which can sort out three color material one time.

SG Belt-Type Plastic Sorting Machine is widely used to irregularly shaped plastic flakes and large plastic bottles.

This kind of plastic sorting equipment also uses optical technology to sort and classify plastics.

X-ray Plastic Sorting equipment is ideal for PET bottle separation, separate the PVC and other bottles from PET bottle


NIR Sorting equipment is ideal for PET and PVC flake separation

NIR Plastic Sorting Machine is capable of identifying polymer materials by type. This device distinguishes and sorts plastics by the difference in infrared emitted from different plastics.

Therefore, it is possible to effectively distinguish all types of plastics.

Key Accessories:

Vibrator: The vibrator ensures that the plastic flakes or plastic particles enter the sorting cabinets evenly, which will prevent the plastics from overlapping each other.

Chute OR BeltChute Chute or Belt is media that gives the target plastic the same speed, which helps the identification system and rejection system accurately position the plastic.

Camera:High-Revolution Industrial cameras can mark plastic color and shape information. This is the basic to separation.

CCD Sensor: Read and identify the color information of each plastic flake and plastic bottles.

CPU Board: CPU Board is a data conversion system and it consists of various CPU Parts. Each little CPU part has a special function.

EjectorsEjectorIt is an execution device. After receiving the instruction of the CPU board, the movement track of different plastics is changed by opening or closing the spray valve to achieve the purpose of separation.


How does plastic Sorting Machine work/ Working Principle

Belt-Type Plastic sorting machine working principle

Graphic 6: Belt-Type Plastic sorting machine working principle

The working principle of all SG plastic sorting machines are similar and it can be divided into two different processing: Identification Processing and Rejection Processing.

Now we take an example to explain the process using separate PVC Flakes from PET Flakes.

Identification Processing: Both PVC and PET flakes are first imaged when raw plastic material entering the plastic sorting cabinet.

Integrated CCD Sensor will read their color information and mark PVC flakes color as X and PET flakes’ color as Y.

Meanwhile, the color information will be transferred into electronic signals and be passed to Rejection processing.


Rejection Processing  

After receiving the information from the identification system, the ejection system will be activated. When receiving the X signal, the CPU reacts quickly and issues an instruction to change the PVC flakes path.

This command is passed to the valves. The CPU integrated into the valves positions the PVC plastic and opens the nozzle to release compressed gas in time to change the movement of the PVC flakes.

Under the action of the external force of PVC flakes, it will escape the original movement track and enter the new acceptance basket;

When receiving the Y signal, the movement track of the PET flakes remains unchanged and continues to slide down to the original acceptance basket, thereby completing the sorting process.
