China Air-cooled Strands Pelletizer System Manufacturer — Granuwel
Air-cooled Strands Pelletizer System is an efficient and energy-saving plastic pelletizing solution suitable for continuous pelletizing of biodegradable PLA/PBAT compounds, PP+CaCO3 modified materials for hollow partition boards, thermoplastic plastics, and certain high-temperature engineering plastics. This system ensures uniform pellet size and smooth surfaces through the process flow: melt extrusion → air cooling → mechanical pelletizing. It is widely used in modified plastics, cable compounds, color masterbatch, elastomers, and recycled plastic fields.
The Granuwel Air-cooled Strands Pelletizer system features a modular design, equipped with high-efficiency cooling fans, precision cutting blades, and an intelligent control system. It meets various capacity demands, enabling low-energy, low-dust, and highly stable modern pelletizing production.
Core Advantages of the Air-Cooled Strands Pelletizer System
Efficient cooling, no water residue
Utilizes forced air-cooling technology, eliminating the drying process required in traditional water cooling methods and reducing energy consumption. Suitable for water-sensitive materials (such as PVC, starch-based biodegradable plastics), preventing pellet water absorption and clumping.
Uniform pellets, excellent flowability
Pellet shape is cylindrical or oblate with precise dimensions (typically 2.8-5mm) and high bulk density, facilitating transportation and subsequent processing. Pelletizer blade speed is adjustable to meet the cutting needs of different plastics.
Energy-saving, eco-friendly with low operating costs
No water resource consumption, more environmentally friendly compared to water cooling systems. Enclosed design reduces dust emissions, complying with green manufacturing standards.
Strong adaptability and easy maintenance
Suitable for various materials including TPE, TPU, PA, PC, PET, etc. Modular structure allows quick replacement of wear parts (e.g., cutting blades, conveying belt), reducing downtime.
Core components of the air-cooling strands pelletizing system
01
Host extruder & Die head

Typical applications of Air-cooling strands pelletizing
01
Modified plastics & High-filler masterbatch
Pelletizing of high-filler systems (such as calcium carbonate, glass fiber, flame retardants), producing dense pellets without bubbles.
02
PLA/PBAT + Corn starch blend pelletizing
Suitable for biomass materials that degrade faster when exposed to water.
03
Color masterbatch & Functional masterbatch
Pelletizing of high-concentration color masterbatch, ensuring uniform pigment dispersion and dust-free operation.
