Our granulation system combines shredding, washing, drying, extrusion, melt filtration, and pelletizing in a modular, scalable layout. It is built in our ISO 9001:2015 factory with CE‑aligned design and Siemens/ABB core components. The line focuses on stable throughput, clean pellets, and controlled energy use. Patented process features and intelligent controls support consistent quality and real‑time visibility. We provide customization and pre‑delivery testing with your materials. Shipments typically depart Shanghai or Ningbo, with most projects delivered in about 60 days.
The design targets reliable performance and fast payback. Digital workflows and modular production improve consistency and shorten delivery. Turnkey services reduce risk from assessment through training and ramp‑up.
Optimized screw and barrel geometry with precise temperature zones keeps the melt steady. Closed‑loop control helps achieve high bulk density pellets with lower energy per ton. Optional heat recovery and high‑efficiency drives further cut operating costs.
Recipe management, alarm analytics, and real‑time OEE are built in. Remote diagnostics, trend charts, and electronic batch records support uptime and traceability.
We use Siemens/ABB motors, drives, and PLCs with original certifications. CE‑aligned guarding and ISO‑based documentation support safe operation and audit‑ready records.
We can supply over 120 complete lines each year. Most projects ship within 60 days. Our team supports installation, commissioning, and operator training for a smooth start‑up.
Configure the plastic pelletizing line to match materials and pellet specs. Modules for washing, extrusion, filtration, and pelletizing are selected to fit each application. We tailor screw design, venting, and pelletizer type.
Front‑end shredding, friction or hot washing, and centrifugal or thermal drying deliver clean, moisture‑controlled feed. Effective contaminant removal improves pellet quality and reduces filter load.
Extruders with optimized L/D and venting remove volatiles, inks, and moisture. Options include vacuum degassing, multi‑stage filtration, and wear‑resistant metallurgy for abrasive streams.
A practical choice for PE/PP films, bags, and rigid flakes. It offers efficient melting, multiple venting options, and simple maintenance.
Best for compounding, masterbatching, or heavy degassing. Co‑rotating systems provide intensive mixing and uniform dispersion at controlled shear.
Select by viscosity, throughput, and target size to balance cost, maintenance, and pellet quality.
Robust and versatile for PE/PP regrind, WPC, and filled formulas. Produces cylindrical pellets with consistent cuts.
Compact and responsive with automatic size control and a clean surface finish. Well suited to film‑grade PE/PP and soft PVC.
Preferred for higher throughputs and precise sizing, especially for sticky or high‑MFI materials.
From manual screens to continuous backflush filters, filtration fineness matches contamination levels. Optional deodorization and vent condensers help reduce odors in post‑consumer streams.
Add automatic dosing, gravimetric feeding, silo transfer, and SCADA integration. Batch reports and energy dashboards support continuous improvement.
The line processes polymers used in packaging, construction, and consumer goods. It produces recycled pellets for extrusion, injection, and sheet lines.
Handles LDPE/LLDPE films, HDPE blow‑mold regrind, and PP woven bags. Optimized feeding and venting stabilize melt pressure and pellet uniformity.
Twin‑screw or carefully vented single‑screw setups maintain IV and manage moisture. Optional crystallization and vacuum systems help protect pellet quality.
Precise temperature control and corrosion‑resistant metallurgy maintain polymer integrity. Water‑ring pelletizing supports consistent pellet shape.
Wear‑resistant screws and barrels plus strand pelletizing deliver clean, cut‑stable pellets for decking and profile extrusion.
Modular extruders and pelletizers scale from smaller cells to higher‑volume production with upgrade paths.
Die and cutter setups produce standard cylindrical pellets or sizes tuned to downstream needs.
High‑efficiency motors, barrel insulation, and optimized temperature control help reduce kWh per ton.
Industrial PLC/HMI with recipe storage, trend logging, and alarm history supports quick changeovers.
Metal detection, buffer silos, and level sensors stabilize loading and protect components.
Recycled pellets feed directly into profile and sheet lines to close the loop.
Safety circuits, guards, and emergency systems align with CE. ISO‑managed reviews and traceability are applied across design and build.
Structured FAT and SAT verify mechanical, electrical, and process KPIs before handover.
Complete manuals, wiring diagrams, parts lists, and maintenance schedules support efficient service.
Q: What materials can this line process?
A: PE/PP films and flakes, PET bottle flakes, PVC regrind, and WPC/composites. The configuration is matched to contamination and moisture levels.
Q: How do I choose between single‑screw and twin‑screw?
A: Single‑screw suits PE/PP streams with simpler melting. Twin‑screw supports compounding, high degassing, and specialty blends such as PET, PVC mixes, or WPC.
Q: Which pelletizer should I select?
A: Strand is versatile. Water‑ring is compact for PE/PP and soft PVC. Underwater fits higher throughputs and precise sizing.
Q: What is the typical delivery time?
A: Most lines ship within about 60 days, supported by modular production and a controlled supply chain.
Q: What utilities are required?
A: Requirements depend on the configuration. Contact our granulation line manufacturer team to review power, water, air, and ventilation for your project.
