China PP Plastic Pelletizing Machine Suppliers - High-Quality Recycling Factory for Plastics Waste Processing
At HG Machinery, we provide you one whole recycling machine solution according your specific need.
How a Plastic Pelletizing Machine Works
🔥
Extrusion
The plastic waste is fed into an extruder, where it is melted and formed into a continuous strand.
❄️
Cooling
The melted PP is cooled, often using cold water or air cooling systems to solidify the strands.
✂️
Pelletizing
The cooled strands are chopped into small pellets using a pelletizing die or cutter.
💨
Drying
Any excess moisture is removed from the pellets to prepare them for further use or sale.
Key Features and Technology
-
1Screws are carefully designed and developed by engineers. The entire machine and every component are fully equipped. The heating circuit uses three fire lines and one zero line.
-
2The screw is designed for the material characteristics — the output is high, the material has good gloss and the particles are full. The whole machine configuration is increased, the service life of the equipment is increased, and the appearance is rationalized.
-
3The reasonable design of the equipment increases production, reduces maintenance time and reduces maintenance costs.
-
4The granulator has the characteristics of high output and low energy consumption. It is equipped with a large torque gearbox and electric motor. It has no dead angle and no iron effect, effectively improves the production capacity and improves the plasticizing effect of plastic. It has single exhaust and double exhaust structure. The dry material, the tide material and the water washing material can fully drain the exhaust gas, so that the particles are strong and full of gloss.
-
5The high-quality electrical and drive equipment makes the equipment safer and more reliable in use.

Frequently Asked Questions
Q What types of plastic materials can the HG Machinery pelletizing machine process?
The HG Machinery plastic pelletizing machine is designed to process a wide range of plastic materials including PP, PE, PVC, ABS, and other thermoplastics. It is suitable for both dry materials, tide materials, and water-washed materials.
Q What is the maximum output capacity of the pelletizing machine?
The output capacity varies by model. The largest model (150mm diameter) can achieve an output of 10–11 tons per 24 hours, while the smallest model (100mm) produces approximately 4 tons per 24 hours.
Q How does the cooling system work in the pelletizing line?
After extrusion, the melted plastic strands pass through a cooling system that uses either cold water or air cooling to solidify the material before it is cut into uniform pellets. This ensures consistent pellet quality and dimensional accuracy.
Q What makes HG Machinery pelletizing machines energy-efficient?
HG Machinery pelletizing machines feature a high-torque gearbox and optimized electric motor configuration, enabling high output with low energy consumption. The screw design is tailored to material characteristics to maximize plasticizing efficiency and minimize power waste.
Q Can the machine handle wet or washed plastic materials?
Yes. The pelletizing machine supports single exhaust and double exhaust structures, allowing it to effectively process dry materials, moist materials, and water-washed plastics. The exhaust system fully removes gas and moisture, ensuring strong, glossy pellets.
Q Does HG Machinery offer customized pelletizing solutions?
Yes. HG Machinery provides complete, customized recycling machine solutions tailored to each customer's specific production needs, including screw design, machine configuration, and full-line equipment setup.
