Revealing the 8 core processes of the strand cooling pelletizing line

🚀 Strand Cooling Pelletizing Line♻️

This equipment is suitable for recycling and granulating a variety of hard plastics, 

such as ABS, PC, PP, PE, etc., providing efficient and stable solutions for the plastic 

recycling industry.

1️⃣ Raw material transportation

The recycled plastic is evenly fed into the extruder feed port by a belt conveyor to achieve

 a stable and efficient feeding process. The automatic conveying system reduces manual 

intervention, improves the continuity and automation level of production, and reduces the

 intensity of manual labor.

2️⃣Melt extrusion

The plastic enters the single screw extruder and undergoes heating, plasticization, extrusion 

and other processes to make it fully melted and evenly extruded.

🔹High-efficiency barrel + optimized screw design: better plasticization effect, ensuring 

high output and low energy consumption.

🔹Wear-resistant alloy material: The core components of the equipment are made of 

high-wear-resistant alloy, and the service life is 1.5 times longer than that of ordinary materials.

🔹Screw material: Made of high-quality nitrided steel 38CrMoAIA, after nitriding treatment, 

it has the characteristics of corrosion resistance, wear resistance, and high temperature 

resistance, which greatly improves the stability and durability of the equipment.

3️⃣Screen changer filtration

The molten plastic passes through the screen changer to effectively filter impurities and 

ensure the purity of the particles, thereby improving the quality of the recycled material.

✅Efficient filtration to improve particle quality

✅Reduce equipment wear and maintenance costs

✅Extend equipment life and improve production efficiency

4️⃣Cooling and shaping

After the molten plastic is extruded from the die head, it forms a uniform material strip and 

enters the cooling water tank, where it quickly cools down and solidifies to maintain a stable 

strip shape. The water tank temperature and water flow rate can be adjusted to meet the 

cooling needs of different materials.

5️⃣Strand pelletizing

🔹The cooled plastic strips enter the strand pelletizer and are precisely cut into particles 

of uniform size.

6️⃣Vibrating screen screening

The plastic particles after pelletizing are screened through a vibrating screen to remove 

dust, oversized or undersized particles, ensuring uniform particle size and stable quality 

of the finished product.

7️⃣Wind conveying

Qualified particles are quickly transported to the storage link through wind conveying 

equipment, which not only improves production efficiency, but also avoids secondary 

pollution and ensures the cleanliness of the particles.

8️⃣ Final storage

The final plastic particles enter the storage silo, providing convenient storage for 

subsequent packaging or direct application.
