The PVC granulating line is an essential system in the plastic recycling and material processing industry. It transforms PVC powder, scrap, or recycled materials into uniform granules that can be reused for pipe, profile, or cable production. Langbo Machinery provides complete PVC granulating solutions designed for stable operation and consistent pellet quality.
A standard PVC granulating line includes a feeding system, twin screw extruder, die head, cooling system, pelletizer, vibrating sieve, and storage silo. Each section works in coordination to ensure continuous and efficient production.
During operation, PVC material is melted and plasticized inside the extruder, where temperature and screw speed are precisely controlled. The molten PVC passes through the die head and is cooled by air or water before being cut into uniform pellets. Air-cooled systems are often used to maintain dry pellets, avoiding moisture absorption during storage.
Process stability and product quality depend heavily on screw design, temperature control, and pelletizing precision. Langbo Machinery focuses on optimizing these parameters to ensure high throughput, energy efficiency, and uniform pellet size.
With modular configurations and automation options, the PVC granulating line can be tailored for different material formulations and capacity requirements, supporting efficient recycling and sustainable production in the plastics industry.
