Twin-Screw Pelletizing Line
1. Product Overview
The Tenglong Co-rotating Parallel Twin-Screw Pelletizing Line is dedicated specialized equipment for plastic modification, color blending and compounding, and core machinery helping Linyi-based modification and biodegradable material factories eliminate production bottlenecks. Adopting co-rotating parallel twin-screw structure, it delivers far superior mixing, plasticizing and dispersion performance compared with conventional single-screw units. It supports multiple processing techniques including glass fiber reinforcement, filler modification, flame retardant modification, color masterbatch production and biodegradable pelletizing. Compatible with modification and pelletizing of PP, PE, PA, PBT, ABS, AS, PC, POM, PPS, PET and various other engineering & general plastics, it is especially optimized for local processing of PLA, PBS and other biodegradable resins, facilitating enterprises to implement Linyi’s bio-manufacturing industrial chain layout plans.
2. Core Technical Advantages
High-Efficiency Twin-Screw Mixing for Premium Plasticization & Dispersion
The co-rotating twin-screw design features excellent self-cleaning property. Combined drag flow and positive displacement flow generated inside meshing zones create intensive shearing and mixing on feedstock within the barrel. Glass fiber, inorganic fillers such as calcium carbonate & talcum powder and functional additives disperse evenly to secure stable physical properties of modified plastics. It effectively fixes long-standing industry defects of uneven mixing and insufficient plasticization troubling Linyi’s modification factories, and excels in high-filler formulations to greatly boost finished product yield.
Multi-process Compatibility for Multi-purpose Production
As a benchmark product among plastic modification pelletizers, the machine supports diversified manufacturing routes: glass fiber reinforcement, filled modification, flame retardant modification, color masterbatch extrusion and biodegradable plastic pelletizing. One single unit covers multiple production requirements for remarkable cost savings. Matching Linyi’s industrial layout for biodegradable plastics, it efficiently processes PLA and other compostable resins to help manufacturers expand biodegradable material business in accordance with Linyi Action Plan for Bio-Manufacturing Industrial Chain Construction, cutting extra equipment procurement expenditure substantially.
Modular Screw Design for Easy Maintenance
Modular screw configuration allows customizable screw combination according to different formulas and processing techniques, fitting Linyi manufacturers’ feature of multi-grade raw materials and varied production crafts. Barrel adopts segmented independent heating with precise temperature control accuracy up to ±0.5℃. Key components are easy to disassemble and replace to shorten downtime and reduce maintenance cost, supporting continuous large-volume mass production and meeting local factories’ pursuit of high operational efficiency.
Water-Cooled Strand Pelletizing Produces Uniform Fine Granules
Equipped with variable-frequency controlled water-cooled strand cutting technology, the unit achieves accurate particle size regulation. Final pellets feature uniform dimension, smooth cutting surface, no interlinkage or burrs and high finished rate, suitable for modified plastics, color masterbatches and biodegradable compounds. For color masterbatch production, outstanding cutting performance guarantees even pigment dispersion without color spots or chromatic aberration, improving product competitiveness to fulfill high-standard production requirements of Linyi’s color masterbatch manufacturers.
