Double-Screw Modified Plastic Granulator

Product Overview

The double-screw modified plastic granulator is a customized co-rotating parallel twin-screw extrusion granulation machine with no fixed price; it is tailor-made according to the customer’s production requirements. This equipment integrates plastic recycling, compounding modification, and functionalization into one, featuring excellent high-shear mixing performance. It can produce high-quality modified recycled pellets and functional masterbatches in a single step, meeting diverse needs for modified plastics production. With its co-rotating twin-screw strong mixing structure, it delivers outstanding modification results, and is equipped with a multi-stage vacuum degassing system that thoroughly removes volatiles and impurities, ensuring stable pellet properties and appearance. Additionally, it can flexibly adapt to various processing requirements such as filling, toughening, coloration, and degradation. Core components are sourced from top-tier brands, resulting in low failure rates and long service life, helping enterprises produce high-value-added modified pellets and significantly boosting product profitability.

Key Equipment Features

This co-rotating parallel twin-screw extrusion granulation machine boasts three core features: First, exceptional mixing performance—thanks to the powerful shear mixing action of the co-rotating twin screws, it can evenly blend different materials, achieving ideal modification effects and satisfying blending needs for filling, reinforcement, compounding, and other processes. Second, excellent self-cleaning capability—the machine automatically cleans the screw and barrel walls during operation, preventing cross-contamination caused by material residue and ensuring purity and consistency across batches. Third, flexible modular configuration—customizable modules can be tailored to suit specific production needs and material types, accommodating diverse processing requirements for numerous material systems and expanding the equipment’s application scope.

Core Advantages

1. One-stop modification production: Enables seamless integration of plastic recycling and modification processing, eliminating the need for multiple sequential steps, shortening the production process, reducing material waste, and lowering labor and energy costs. Compared to traditional multi-step modification processes, this approach cuts the workflow by 40% and reduces labor and energy expenses by 25%.
2. Superior modification and impurity removal: The co-rotating twin-screw strong mixing structure ensures excellent modification results, while the multi-stage vacuum degassing system thoroughly removes volatiles and impurities, keeping pellet impurity levels below 0.8%. This allows direct supply to high-value customers in automotive, electronics, and other sectors, addressing industry pain points where single-screw equipment struggles with poor mixing and impurity removal, unable to produce premium modified materials.
3. Strong process adaptability: Flexibly accommodates various processing needs such as filling, toughening, coloration, and degradation, covering applications like filler modification, reinforcement modification, masterbatch preparation, and compounding modification, thus meeting diverse demands for modified plastics production.
4. Stable, durable, and low-failure-rate: Core components are sourced from top-tier brands like Siemens, ABB, and NSK, enabling over 7,500 hours of stable annual operation, boosting production efficiency by more than 50%, with low failure rates and extended service life—solving issues of unstable performance and inconsistent batch quality common in standard equipment.
5. Enhanced product value: Produces high-value-added modified pellets, increasing the market price of finished pellets by over 18% and significantly improving profit margins, helping companies overcome the challenge of low added value in recycled pellets and their inability to enter high-end downstream markets.

Application Fields

This equipment finds wide-ranging applications across four major processing categories:
First, filler modification—compatible with various inorganic fillers such as calcium carbonate, talc, barium sulfate, titanium dioxide, ceramic powder, wood powder/plant fibers, producing filled modified plastic pellets.
Second, reinforcement modification—supports adding short glass fibers, long glass fibers, carbon fibers, and other whisker-like reinforcing materials to manufacture glass-fiber-reinforced pellets and other reinforced modified plastics.
Third, masterbatch preparation—capable of producing carbon black masterbatches, color masterbatches, flame-retardant masterbatches, degradable masterbatches, and other specialized functional masterbatches.
Fourth, compounding modification—suitable for thermoplastic/elastomer, polymer alloy, and cable material processing (including PVC cables, low-smoke halogen-free cables, PE insulation/sheath materials, PE cross-linked cables, and specialty cables), meeting diverse compounding modification needs.

Target Customer Groups

The target customer base for this double-screw modified plastic granulator includes manufacturers of modified plastics, high-end recycled pellet processing plants, functional masterbatch producers, degradable plastic companies, and suppliers of automotive/electronic component materials. These enterprises all have demand for high-quality modified plastics, functional masterbatches, or premium recycled pellets, and the equipment’s one-stop production capabilities, superior modification performance, and high-value-added output precisely address their production challenges and profitability needs.

Specific Application Scenarios

Specific application scenarios include plastic recycling and modification, manufacturing glass-fiber-reinforced pellets, producing color/masterbatches, compounding degradable plastics, PET high-end recycling granulation, and making filled/toughened modified pellets. In plastic recycling and modification scenarios, recycled plastics can be directly processed for modification, enhancing the quality and added value of recovered materials. In glass-fiber-reinforced pellet production, the robust mixing structure ensures uniform blending of glass fibers and plastics, yielding stable-performance glass-fiber-reinforced pellets. In degradable plastic compounding, degradable materials can be blended with other plastics to produce compliant degradable plastic pellets.
