Plastic Sorting Machine

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

It quickly removes impurities from plastic mixtures and classifies plastics by type and color. For example, it can pick out blue PET Flakes from a crushed PET bottle. The machine can also:

  1. Remove Metal, Paper, Dust and other impurities from the plastic mixture;
  2. Separate solid plastic from transparent Plastics;
  3. Classify all types of plastic including PVC, PET, HDPE, LDPE, and PP.

Machine Types

Plastic Sorting Machines can be divided into two types according to their sorting technology:

  • CCD Color Sorters;
  • NIR(Near-infrared) Plastic Sorting Machine;

Belt-Type Plastic Color Sorter

Graphic 1: Color Sorting VS Type Sorting in plastic recycling

CCD color sorter uses the color difference of plastic to distinguish and classify the target objects; However, NIR sorting machine uses various plastic infrared wavelength differences to sort.


Every SG Plastic Color Sorter has a 10” of the visualized touch screen on the front of the machine. You can use it to set and adjust the parameter.

SG plastic color sorter can preset a twenty sorting scheme. This function allows you to quickly set the parameter and start a similar sorting process.

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

Optical Sorting equipment is ideal for waste plastic recycling

The optical sorting machine can help the plastic recycling industry to solve two of the most headaches:

  • Remove the impurities;
  • Classify the plastic Quickly.

Manual operation is hard to adapt to large plastic recycling because it is too slow. Traditional washing can not remove solid impurities.

Now you are able to use a CCD Color Sorter to remove the solid impurities by color difference. Also, you can use the NIR sorting machine to classify the plastic by type.

SG CCD optical sorter has two different structures: Belt-type color sorter and Chute-type color sorter.


§ Chute Color Sorter


The chute-type color sorter has a great feature – Chute. The Sorted Plastics must go through the chutes before entering the sorting cabinets.

The chute has a  specific width and each of them is divided into 64 channels. So it is ideal for small-size plastic such as PET pellets and PET flakes.

Now there are twelve kinds of chute-type plastic color sorter available. They provide 12 different sorting capacity that ranges from one time to 12 times to mini color sorter.  And mini color sorter can separate 0.5 ton of plastic mixture in an hour.

Chute-Type Plastic Sorting Machine

§ Belt Color Sorter


SG Belt-Type Plastic Sorting Machine works much better than chute-type when meeting the plastic of irregularly shaped or bigger size.

This kind of plastic sorting equipment transports the target objects by a horizontal belt without any chutes. So it does not have any size limits.

Belt-Type Plastic Sorting Machine

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.

NIR Plastic Color Sorter and Recycleable Plastic

Graphic: NIR Color Sorter and Recyclable Plastic

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

– PP



it allows separating one type of plastic in once sorting and sorting capacity ranges from 0.5 ~ 6 tons per hour.

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.


Working Principle

How does plastic Sorting Machine work

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 is 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 positions of the valve 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.

In 2019, recycling of plastic deadly needed because waste plastic can cause pollution.

Plastic recycling is complicated as compared to other materials like paper, glass, and aluminum.


Why is plastic more difficult to recycle?


Because plastic is a mixture of different kinds of polymers fiber, and polymer requires more energy and process to recycling.

Different types of plastic have different properties, so be careful when you want to separate waste material.

Recycled Plastic Flakes

Graphic: Recycled Plastic Flakes Mixture

Disposal or recycling process of plastic waste has emerged these days because plastic is a non-degradable material.

As you know, Plastic cannot decompose naturally, so we need to manage it by sorting and recycling process.

The plastic sorting process managed the mess of plastic around us and especially on sea beaches.


What percentage of plastic is recyclable?

In 2015 it was estimated about 55% of the world’s plastic waste disposed of, 20% recycled, and 25% burned.

You can get a decent idea from the above data in 2019 how much plastic we need to recycle.

Plastic Waste Generation By Industrial Sector 2015

Plastic is one of the important things these days, now we use 25 times more than 50 years back.

So we need to handle plastics responsibly to minimize the pollution in the environment.

We can manage waste plastics by recycling and reusing at a very reasonable cost.

Different types of plastics we need to recycle

  • Sorted by polymer type
  • Melted
  • Shredded
  • Washed
  • Made with new products.



Typically recycling of plastic is a two-stage process

1- Manual procedure in which we can sort plastic automatically and removed contaminants.

2- Once the process of cleaning completed, it can shred into flakes

If you want to deliver quality products in a short time you need to rely on machines, it will help to maintain customer satisfaction.

Typical Plastic recycling Process

Better quality always attracts more customers, so automotive machines are far better in comparison to manual sorting machines.

Sorting machines can operate quickly and more cost-efficiently while ensuring the quality of the product is never compromised.


1.3 Which Process Uses Color Sorters?


The Plastic Recycling Process

Plastic sorting and recycling is the most uncomplicated process in which different steps, including:

1- Collecting

2- Shredding

3- Washing

4- Melting

5- Pelletizing

This is a matter of fact, a different type of plastic product needs a different process of sorting.

Normally the plastic recycling industry follows these two steps:

1- Choose the automatic sorting process or manual to remove all wastes from the plastic material.

2- You can melt plastic material directly and form a new shape or shred into the flakes.


– The Type of Recycling Plastic

There are six types of recycling plastics, have a look at some of the example products.

PP (Polystyrene)- 

It can be solid or foamy like lunch boxes, food containers, hotpot, or ice cream containers.

PVC (polyvinyl chloride) 

This is low flammable material, resists to most of the chemicals like juice bottles and squeezable bottles.

PS (Polystyrene)

Form of plastic used in laboratory equipment, hot drink cups, and plastic cutlery, and yogurt containers.

PET (Polyethylene terephthalate)

The most common thermoplastic polymer, also known as PETP and PETE generally used in the fiber of clothing, fruit juice bottles.

LDPE (Low-density polyethylene)

It was first grade of polyethylene, used in toys, Shampoo bottles, carriage bags, garbage bins, and squeezed bottles.

These days PETE, HDPE, and PVC thermoplastic recycled efficiently, but PS, PP, and LDPE sometime stuck in sorting machines.

Which products can be recycled or not is a big question when we discuss plastic sorting & recycling some types are not allowed to be recycled.

Chapter 2: Types of Color Sorting Machine


2.1 NIR Sorting Machine


First Near Infra-Red sorting system used to sort and recycle material like plastic, paper, and textile according to types.

The new technology level allows it sort of PET plastic from the mixture.

NIR Technology is based on reflectivity within the range of 1100 to 2100. During the range, all plastic materials have their properties, keep one thing in your mind this range of wavelength is not visible to the human eye.

Modern sorting systems can sort different types of plastics easily, such as PP, PS, PC, or PVC, even also helps to identify materials that are cellulose-based like paper, cardboard, or wood, and fibers.

How does it work?


When Near Infra-red light hit to the plastic material, it reflects towards internal camera sensor.

After detecting the faulty particles, air pressure ejects the defected pieces and collect fine material.

NIR technology used to separate PET plastic from a plastic mixture.

Chapter 3: Plastic Recycling machines


Both color sorter and plastic recycling machines are used in plastic recycling. The best thing is both equipment work together will create higher value and provide better quality products.


“The two machines are different. The plastic recycling machine is used to the process that gets plastic waste to plastic granule, and the other equipment is applied to the process that separates the different colors.”


3.1 PET Bottle Recycling System

PET bottle recycling is nowadays widespread also becomes more efficient.

A lot of plastic used in different products and can remake to utilize again and again.

Plastic recycling helps to reduce environmental pollution, save energy, and helps to deal with the emission of carbon dioxide.

Plastic Recycling Process


The plastic recycling process divided into different steps. These steps are the same for many recycling processes, but few steps can be combined or omitted in some conditions.

1. Collection

The initial stage in the recycling procedure is always collecting the plastic material that will be recycled.

This step is dependent upon organizations, restaurants, and the general population to discard their plastic waste in the right spot.

If plastic waste disposed of in ordinary trash bins, it won’t be recycled, so it is critical to isolate the regular waste and plastic waste.

Moreover, it is ideal for governments to have a recycling collection system that goes to individuals’ homes or organizations to collect plastic waste.

If this is not possible, the local collection focuses on plastic ought to be simple for the public to make it useful and easy for people to dispose of plastic waste accurately is paramount in advancing recycling.

As we know, you will collect lots of types of plastic in the plastic collecting process. But most plastic can not be recycled.

In PET bottle recycling processing, this sorting process is not necessary.

If you use Plastic color sorter PET bottle contains three parts: cap, bottle body, and plastic label.

Once the bottle broke, the color sorter can separate the bottle flakes and cap according to their color.

 2. Washing

Just like with garments, organic products/vegetables, and numerous different things, plastics must be washed before they additionally handled.

The objective of this step is to expel impurities and everything that isn’t produced using plastic.

Most containers and packages have marks or labels, adhesive, or even food residue that must be evacuated.

This non-plastic waste can’t be recycled and can make the final product to have poor structural integrity.

3.2 How plastic color sorter works?


 Working Principle


The principle for both CCD color sorter and NIR Sorting machine is similar, and the difference is using different camera technology.

The plastic color sorters are machines that are used to sort plastic particles. They separate the elements according to the color and using ejectors to divert particles that are not up to the mark.

In the plastic sorting industry, color sorter helps to separate colorless and colored PET (polyethylene terephthalate) and HDPE (High-density polyethylene) flakes.

It helps to distinguish mix color plastic flakes with sensor-based sorting technology but in different materials.

The plastic industry based on two types of sorters.

Chute color sorters help to sort or separate plastic pallets, on the other side, belt color sorter to sort plastic flakes.

It may be belt type, or chute type plastic wash, separate, and granulated.

Both types can work, but chute-type is better for granulate plastic because it’s cost-effective.


 Technologies used in the plastic recycling sorting process

Polyvision detection technology 

With the help of detection technology, we can analyze chemical composition precisely, which separates fine material with high accuracy.

Custom-built visible Cameras 

Custom-built high-resolution cameras remove the unwanted colors from the plastic material like PET flakes and polythene material.



NIR plastic sorting system based on NIR spectrometry technology, which helps to classify each flake of recycled plastic products.

This is very efficient technology sometimes provides 95% quality maintenance after processing.

NIR Technology Features


Integrated MMI

-NIR sorter provides more comfort when it attaches to the high-resolution touch screen

-Fast Sorting Technology

-The NIR sorting technology integrated with proper equipment to avoid noise and for better quality and accuracy.

-NIR machines help to separate the type of plastic according to the material.

On the other side, sorting with a CCD camera is also an efficient way. Still, it can sort your products according to the color difference.




Resizing comprises of shredding or crushing the plastic waste into little particles.

It expands the surface area of the plastic, making it simpler to process, reshape, and transport if necessary.

Moreover, it gives recycling facilities one last chance to remove any non-plastic waste that has endured the initial three stages of processing.

It frequently is done with metal detectors or magnets that will help to remove any remaining metal in the mixture.

Identification and Separation of Plastics

The identification and separation of plastics is the point at which the little plastic particles are tested to decide their quality and class.

The first quality test is density. It finished by floating the particles in a huge tank of water.

Particles less thick than water will float, and increasingly dense particles will sink.

Next, their air classification resolved. Air classification is a term for how thin or thick a molecule is.

The process mentioned above, completed by dropping the particles into a little wind tunnel. The small pieces will fly higher up the tunnel, and greater ones will remain lower.

Two different features of plastics usually tested for are their melting point and color. These controlled by collecting and analyzing samples from each group of plastic particles.


The last step in the recycling procedure is often considered the most energizing since it is the point at which the plastic particles made into recycled materials used for future production.

Compounding is the point at which the little particles are crushed and melted together into plastic pellets.

The pellets can then be able to use in the creation of other plastic products.

Throughout this procedure, the plastic might be moved to various plants that have practical experience in multiple steps of the process.

It could be energy-intensive, and the better instructed we are about the procedure, the more we can reduce the time and energy it requires.

Recycling of a Plastic Bottle

Suppose that you have quite finished drinking water from a commercial disposable (however recyclable!) water bottle.

As you place your unfilled water bottle into your home recycling bin as you generally do, you wonder,

“What will happen to this water bottle after I’m done with it?”

In the first place, your bottle must gather by a recycling facility.

It can happen when recycling assortment drivers get your plastic recycling bin on your check before your home, or when you carry your recyclable waste to a local recycling office.

Next, if your local recycling organization has executed a Single Stream Recycling System, by which all materials gathered together, these materials must experience an arranging procedure to isolate various materials, for example, glass, paper, or metals.

Regularly, most of this arranging procedure is done naturally by machines.

Yet, it might also incorporate one manual sort to dispense as much contamination of the materials as could be expected.

Since there are various sorts of plastics in use today, the entirety of the plastic materials in a recycling office must be isolated by type.

Your plastic water bottle will probably be assembled with the other plastic materials made with #1 polyethylene terephthalate (PET or PETE) plastic.

Unfortunately, particular sorts of plastics not as effectively recycled as different kinds of plastics.

Many recycling offices don’t have equipment that can deal with each type of plastic.

Thus these things might be offered to another office that can recycle them, or they may wind up in a landfill.

Next, your water bottle will go to the area of the recycling office where it will be ground up into chips or pieces. And the plastic will then be washed to dispose of any label or remaining buildup.

The plastic is dried, softened, and shaped into pellets, which can use for assembling new items.

Recycled plastic pellets would then be able to be offered to organizations and used to make various items.

A few items produced using recycled plastic bottles incorporate artificial fleece, designed wood items, covering, floor mats, tiles, furniture, engine oil, cleanser bottles, pipes, and buckets.

Your water bottle will presently be given another life as something different! Plastic bottle recycling is then certainly worth your effort.


3.3 Film Recycling System


Film products tend to be classified either by their composite materials or by wide product groups. The Packaging and Films Association (PAFA) uses three expansive item definitions outlined below regarding their use in household packaging applications.

Plastic Film

Generally made as sheet material, for example, stretch and stick wrap for food protection and bundling.

Plastic Bags

A wide range of packs from buyer items, for example, sandwich/ freezer bags to transporter packs gave by retailers.

Plastic Pouches

These are used in food packing and generally sealable and sufficiently strong to be self-supporting.

The material helps keep items fresh, along with extending their utilization by date and preventing contamination when handled.

It is hard to decide every polymer type utilized by the sector because of the variability in packaging film qualities, yet dependent on the data assembled polyethylene (PE), both as low and high-density PE, is the most widely recognized.

Household Plastic Film 

Composite plastic films used for the packing of food, it can be produced from layers of various polymers. It might be bonded with different materials such as aluminum foil. Added substances can be applied to, for instance, seal in moisture.

The most famous biodegradable plastic is Polylactic Acid (PLA). Oxo-degradable plastics are ordinary polymers with added substances advancing degradation after some time.

Towards the beginning of the sorting procedure, plastic film handpicked out of the recycling stream. While the extra work is costly, especially as the recouped film is of little worth, it is crucial to evacuate this material as soon as possible.

If a pickers miss a film bag toward the beginning of the procedure, it can get folded over the MRF’s fiber sorting screens.

When the screens become obstructed by the plastic film, their capacity to sort materials decreased, which reduces material quality after some time as the examples of pollution increment.

In extreme cases, the screens become seriously blocked and need intensive cleaning, which causes plant downtime.


-The film system specially designed for washing plastic films with contamination levels, which exceed 80%. It minimizes the recycling water flow rate and evaporation.

-The pre-treatment module of the framework is equipped wear-resistant design to amplify structure uptime.

-Pre-shredding and pre-washing frameworks expel an enormous level of rough materials (sand, grits, and so on.) to protect the rest of the framework.

-Shredding framework is designed mainly for film materials to make a uniform molecule size, which is simple for washing and drying.

-Underwater force-washing paddles in our washing tanks expand the washing productivity.

-The drag chain discharge device controls the material discharge speed and limits the water volume sent to the drying procedure with the item.

-Mechanical (diffusive and crushing) and warm drying systems control the moisture substance of the finished product.

-At < 5% moisture, the material is reasonable for top quality pelletizing.

-Shredding, fast washing, and drying stages are streamlined to avoid over-processing, which can cause material disaster.

Problems with Film Recycling

The recycling segment faces a consistent issue with contamination by materials that can’t be recycled being stirred up with recyclates.

Plastic film and bags are reasons for contamination; however, different things, for example, crisp parcels, dirty nappies, and unwashed glass jars or plastic tubs, are main issues.

Plastic bags are produced using thin, flexible sheets of plastic film, ordinarily under 10mm thick.

At the point when these thin plastic films enter a conventional materials recycling facility (MRF), they can truly harm the proficient activity of plant and machinery.

The creation of films and their high rigidity implies that such materials can immediately get wrapped or tangled around moving or spinning apparatus.


3.4 How does a colour sorter work in a plastic recycling system.


The plastic sorting machine is specially designed for the removal of impurities and separate the plastic by color and its types in a quick way.

A belt-type plastic color sorter machine is designed to sort and separate different colorful plastic recycling flakes.


-Intelligent CCD multi work belt-type color sorter can not just meet the scope of chute type color sorter, yet additionally can sort the material for ethereal, unpredictable, effectively broken, exceptionally wet material, which have explained the little gravity speed brought about by lightweight of these extraordinary materials.

-Suggested Applications: Recycled Plastics, Best for light PVC, PP.

-The belt speed could be up to 4m/s, which can meet the requirements for the sorting output.

-Full-colour line scan technology 2048 combines the material’s colors and shapes. It could provide both color sorting and shape sorting for various materials. The varieties of sorting colors can set freely.

The optical color sorter is designed to deliver the best performance in the most challenging environments:

  • Operating and feeding system
  • Valve driven mode and original natural blowing nozzle
  • The ventilation system and unique air suction
  • Wide conveyor belt
  • The light source processing system
  • Operating system
  • Cooling system
  • Image processing



Machines to be packaged to endure transportation under severe conditions. The handling instructions designed to protect the machine in the harsh moments during transportation, uploading, and installation.
