Double-Screw Degradable Plastic Granulator

Product Overview

This product is a co-rotating parallel twin-screw extrusion granulation machine under the PURUI brand, originating from Nantong. It is a customizable double-screw degradable plastic granulator with no fixed price; pricing will be determined based on the customer’s production requirements. The equipment integrates plastic recycling, compounding and modification, and functionalization into one system, featuring excellent high-shear mixing performance. It can produce high-quality modified recycled pellets and functional masterbatches in a single step, meeting the processing needs of various material systems.

Core Features

The co-rotating parallel twin-screw extruder boasts three core features: First, outstanding mixing performance—thanks to its powerful shear-mixing structure, it ensures thorough blending of materials, guaranteeing uniform and stable modification results; second, excellent self-cleaning capability, effectively preventing material residue and reducing cross-contamination between batches, thus ensuring product purity; third, flexible modular configuration, allowing adjustments to suit different processing needs and accommodating diverse material types. Additionally, the equipment employs a multi-stage vacuum degassing design, thoroughly removing volatiles and impurities, resulting in strong pellet performance and stability, while also being adaptable to various processes such as filling, toughening, coloration, and degradation.

Third, it can flexibly adapt to various process requirements—including filling, toughening, coloring, and degradation—meeting the diverse processing needs of different materials. Fourth, key components are sourced from top-tier brands, ensuring low failure rates and long service life, with annual operating hours exceeding 7,500, boosting production efficiency by over 50%. Fifth, it produces high-value modified pellets, increasing the market price of finished pellets by more than 18% post-modification, substantially improving profit margins and helping businesses expand their product profitability.

Application Fields

The equipment finds broad application across numerous processing scenarios: In the field of filler modification, it accommodates calcium carbonate, talc, barium sulfate, titanium dioxide, ceramic powders, wood flour/plant fibers, and other inorganic fillers; in reinforcement modification, it handles short glass fibers, long glass fibers, carbon fibers, and other whisker-based reinforcements; in masterbatch production, it manufactures carbon black masterbatches, color masterbatches, flame-retardant masterbatches, degradable masterbatches, and other specialized functional masterbatches; in compounding modification, it is suitable for thermoplastics/elastomers, polymer alloys, and cable compounds, including PVC cables, low-smoke halogen-free cables, PE insulation/sheath materials, cross-linked PE cables, and specialty cables. Furthermore, the equipment can be applied to plastic recycling and modification, fiberglass-reinforced pellet production, color/funtional masterbatch manufacturing, degradable plastic compounding granulation, high-end PET recycling granulation, and other specific production applications involving filling and toughening modifications.

Target Customer Base

The primary target customers include manufacturers of modified plastics, high-end recycled pellet processors, functional masterbatch producers, degradable plastic companies, and suppliers of automotive/electronic component materials—businesses that place high demands on material modification effectiveness, product purity, production efficiency, and added value. The equipment’s features and advantages precisely align with these production needs.

Solutions to Industry Pain Points

Addressing many persistent challenges within the industry, this equipment offers effective solutions: First, it resolves the issue of poor mixing and impurity removal found in single-screw machines, which cannot produce high-end modified materials. By leveraging powerful shear mixing and multi-stage vacuum degassing, it ensures both modification quality and pellet purity, enabling the production of premium-grade modified pellets. Second, it addresses the problem of lengthy, costly, and wasteful multi-step modification processes by integrating recycling and modification into a single streamlined workflow, shortening the process by 40% compared to traditional multi-step methods while reducing labor and energy costs by 25%. Third, it overcomes the challenge of low added value in recycled pellets, which often struggle to penetrate high-end downstream markets. The high-value modified pellets produced can directly serve high-margin customers in sectors like automotive and electronics, enhancing overall product profitability. Fourth, it mitigates the instability and batch-to-batch variability common in standard equipment by using top-tier components, ensuring robust equipment stability and annual operating hours exceeding 7,500, thereby maintaining consistent product quality across batches.
