Pet Flakes Washing Line Process

The PET flakes washing line is a recycling machine that processes recycled PET bottles (from beverage companies) into clean, dry, and transparent PET flakes. The PET flakes are then used to produce polyester staple fiber (PSF), polyester filament, PET sheet, and other downstream products.


How does the PET bottle recycling process work?

The primary process of the PET bottle recycling process includes crushing, washing, drying, and packaging.

1. Crushing: Crush the waste bottles into small pieces; a crusher or a shredder can crush them.

2. Washing: Remove labels and glue from bottles by high-speed friction washer; remove oil stains with hot water; remove impurities with sink/float separation system; remove dirt by friction washer again.

3. Drying: Dry the washed flakes to remove water content in the washed flakes in a hot air dryer system or centrifugal dryer system. The dried chips are clear and transparent without any moisture.

4. Packaging: Package the final products into different sizes according to needs.

1. Conveyor: The conveyor belt is used to transport waste plastic bottles to the crusher.

2. Crusher: The crusher is used for crushing plastic bottles into flakes with a thickness of about 2-3 mm.

3. Trommel: Used to remove large pieces of dirt from the crushed flakes; for example, crushed bottles pass through two channels, one for fine material and one for coarse material.

4. Friction washer: Used to scrub pet flakes with water, soap, or detergent, which can easily remove dirt and oil on plastic chips.


How to Wash Pet Flakes?

This is a line that processes plastic bottles into PET flakes. The whole line includes a bottle crusher, a hot washer, a flotation machine, a dryer, and a final separator.

1. The bottle crusher breaks down the pet bottles into smaller pieces. This makes it easier to process them further in the other machines.

2. The hot washer is used to wash the PET bottles to clean and ready for the next stage of processing.

3. The flotation machine separates any contaminants from the PET flakes using bubbles in water as an agent of separation (like oil and water).

4. The dryer removes excess moisture from the PET flakes before they are sent for further processing or packaging purposes.

5. The final separator removes any remaining contaminants and sorts them according to size so that they can be recycled accordingly.


How to Solve the Noise Problem in the Production of Pet Flakes Washing Line?

The noise problem of the production of pet flakes washing lines is very complex. Here, we learn from the experts in the field to explain the causes of the noise and solve them.

1. The primary source of noise:

(1) The friction between the material and the material and the equipment;

(2) When the shaft rotates, it produces an impact sound;

(3) When the fan passes through, it will produce airflow sound;

(4) When various valves are opened or closed, there will be a sound when passing through.

2. Noise control measures:

1. Choose a quality gearbox. A good gearbox can reduce the noise generated by friction. There are many manufacturers offering gearboxes on the market, but we have to be more careful when choosing them.

2. Reduce friction by lubrication. Lubrication can play a role in reducing conflict and reducing noise. However, it is best not to add too much oil during lubrication, as excessive fat will increase energy consumption and affect production efficiency.

3. Check whether the pitch is correct during installation. The gap between the rotor and the blades is too large or too small, resulting in an increase in noise during operation. If it is found that there is a problem after installation, it should be adjusted in time to ensure that it meets the design requirements.

How to Make Money with a Complete Pet Flakes Washing Line?

Plastic recycling is a very profitable business. It’s easy to collect plastic waste if you take some steps beforehand.

For example, you can learn the following information about plastic waste:

• Where to collect the plastic waste – The best places are local dump sites, waste collection yards, large grocery stores (particularly those without their own recycling plant), and small-scale industries like manufacturers of plastic products or plastic molding companies.

• What kind of plastics are available – There are six types of plastics used commonly – PET, HDPE, PVC, LDPE, PP, PS. The first five are used to manufacture different products. The last one is used as foam in packaging materials and dinner plates/glasses etc.

• Which type of plastics can be recycled easily – PET and HDPE are the easiest to recycle because they can be easily re-processed. Most other types of plastics require special treatment before they can be re-processed.

• Which type of scrap has the highest value – In India and many developing countries, PET bottles have the highest recycling value because they are considered reusable after sterilization by boiling them in water for about an hour. In developed countries where tap water is safe to drink, people don’t bother about sterilization and hence prefer glass bottles. Glass bottles are also suitable for food products like milk and juice.
