Hot-Cut PVC Granulation Line

PVC pelletizing machine is used to granule all type PVC materials, the mixed PVC materials are pushed axially through the gaps between the screw and barrel by the screw threads, causing the material particles to agglomerate into spheres by extrusion pressure.

Through the granulation die of the PVC granulator machine and hot-cut into uniform granules by a hot-cutting system. After cutting, the PVC granules are transported by an air conveying system and pass through a cooling and screening unit of the PVC granulation line, finally obtaining high-quality qualified granules.

PVC granulator machine adopts the SJSZ series high-efficiency twin-screw extruder, which features strong mixing capability, uniform plasticizing, and stable output. It can produce PVC granules with consistent quality and offers excellent adaptability to different PVC formulations.

PVC granulation line is equipped with a variable frequency speed control system with five-level speed regulation, which effectively reduces energy consumption while maintaining stable production output.

From feeding and granulation to cooling and screening, the PVC granulation line operates in a fully coordinated process, reducing manual intervention and significantly improving production efficiency.

Mixing: Raw materials are first mixed according to the formula and then fed into the PVC granulator machine through a feeding system. Inside the screw barrel, the material is heated and plasticized, and then conveyed forward by the rotating screw.

Special Screw and Barrel : PVC granulator machine adopts a high-performance conical twin-screw extrusion system. The screw structure of the PVC granulation line is optimized for different PVC blends to achieve efficient plasticization and uniform mixing, ensuring smooth material flow and stable extrusion performance.

Advanced Pelletizing Head : PVC granulator machine is equipped with a high-precision pelletizing die head that ensures molten PVC material is extruded evenly. This design guarantees uniform particle size (Φ3–4 mm) and a smooth appearance, making the PVC granulation line suitable for various PVC granulation production requirements.

Dust Removal System : PVC granulation line features a cyclone separation dust removal system. This system in the PVC granulator machine effectively separates dust during the production process, maintains a clean working environment, and improves raw material utilization.

Automated Granulation Process : From feeding, extrusion, granulation, cooling to screening, the PVC granulation line operates with a highly automated process. The PVC granulator machine significantly reduces labor costs while improving overall production efficiency.
