Powerful air-cooled collection system featuring physical cooling and cyclone separation: Material is continuously fed into the storage hopper via an overhead high-pressure blower pipeline (the transparent, reinforced conveying hose is visible on the left side of the video). Utilizing aerodynamic principles, the high-speed airflow creates a cyclone within the hopper; this not only effectively separates the material from the air but also dissipates significant residual heat from the granule surfaces, allowing for secondary cooling before the granules settle and preventing them from sticking together.
High-quality stainless steel construction: The storage hopper is constructed entirely from mirror-finish or brushed stainless steel, offering exceptional wear and corrosion resistance. This ensures the material remains free from secondary contamination during handling, making the system ideal for industries requiring high material purity. Fully enclosed safety electrical cabinet: Housed in a standard blue, dust-proof, industrial-grade powder-coated enclosure, the cabinet integrates a high-efficiency variable frequency drive (VFD), a PLC control system, and overload protection components. This design ensures operator safety while enabling synchronized speed matching across the entire production line.
Flexible material transfer mechanism: The video demonstrates a convenient process for weighing and discharging bagged material. Clean plastic granules fall precisely from the hopper bottom into packaging bags; on-site operators need only provide minimal assistance to complete the fully automated, closed-loop process spanning granulation, air cooling, storage, and packaging. High-efficiency pelletizing unit: The pelletizer located in the center of the frame delivers powerful performance, featuring a cutter shaft that has undergone precision dynamic balancing.
High-power centrifugal blower: A white, high-power air-cooling centrifugal blower is compactly connected to the right side of the main unit. This blower is the core of the system’s air-cooling function, generating a continuous, stable, high-pressure airflow that instantly propels the hot plastic granules—freshly cut by the blades—into the conveying pipeline.
Excellent on-site experience: Although multiple personnel are gathered around the machine for technical discussion in the video, the unit operates smoothly with noise levels well within industrial standards. Furthermore, it eliminates the issues of pervasive steam and slippery floors often associated with traditional water-cooled granulation, significantly optimizing the factory’s production environment. Traditional plastic pelletizing often relies on water-cooling methods (such as water-ring or strand pelletizing). These not only require massive cooling tanks and dewatering equipment but also entail challenges regarding wastewater treatment, high energy consumption, and excessive moisture content in the finished pellets.
Our air-cooling system enables a “water-free” operation:
Zero wastewater discharge: Aligns with global environmental protection and carbon neutrality policies.
Moisture-free finished product: Pellets are dry immediately upon discharge, ready for direct packaging or immediate use in subsequent injection molding or film blowing processes, thereby saving on costly electricity for drying. 🌟 Precise temperature control enhances pellet fullness by 20%. 🌟 Modular industrial design reduces the footprint by 30%, ensuring durability and ultra-low maintenance costs.
Core cutting blades: Manufactured from highly wear-resistant alloy steel, offering a service life 3–5 times longer than standard blades.
Airflow conveying pipes: A combination of thickened, wear-resistant flexible hoses and rigid stainless steel piping minimizes pipe wall abrasion caused by high-speed material flow. Suitable materials: PP, PE, HDPE, LDPE, ABS, PET, EVA, etc. This air-cooling pelletizing system is widely used in the following sectors:
Recycled plastic facilities: Reprocessing waste plastic films, woven bags, and regrind into high-quality primary or secondary recycled pellets.
Modified plastics enterprises: Rapid cooling and shaping during the pelletizing of filled, blended, or alloyed plastics.
In-plant scrap recovery: Enabling factories to implement “immediate recovery, immediate pelletizing, and immediate re-introduction” of production line waste, creating a green, closed-loop system within the facility.
