Product Introduction
Plastic Granulating Line is a device used for plastic recycling, modification granulation, or direct pelletizing after extrusion. It uses air cooling instead of traditional water cooling and is suitable for heat-sensitive materials (such as HDPE, LDPE, LLDPE, etc.) or plastic granulation scenarios where water washing is not required. This machine can granulate waste materials and scraps such as plastic film, stretch film, and bubble film for reuse in production, making it the latest ideal granulation equipment for plastic recycling.

Workflow
Melting & Extrusion
Plastic raw material is melted and homogenized in the extruder, then forced through a multi-hole die head to form continuous strands.
Strand Cutting
The extruded strands are immediately cut into uniform pellets by a high-speed rotary cutter at the die face.
Cooling & Solidifying
The hot pellets are rapidly cooled and solidified by an air or water stream to prevent sticking and set their final shape.
Drying & Collection
The cooled pellets are dried (if water-cooled) and then conveyed as the finished product for packaging or further use.
Core Components
1.Extrusion System: Employs a single-screw extruder with a cylinder-operated feed inlet.
2.Extrusion Die: Multi-hole die: The melt is extruded into strips (1-3mm in diameter) through the die holes.
3.Pelletizing System: A high-speed rotating cutter (adjustable speed) cuts the plastic strips into pellets (1-3mm in length).
4.Air Cooling System: Cold air is directly blown onto the pelletizing area to quickly cool the pellets and prevent sticking, then the finished pellets are stored in the storage silo.
Key Features & Benefits
1.Advanced Air-Cooled (Dry-Cut) Pelletizing
Benefit: Plastic Granulating Line Eliminates the need for water, preventing material degradation in heat-sensitive plastics and removing the costly, energy-intensive steps of water treatment and drying. Ensures pellet integrity and high bulk density.
Feature: Integrated centrifugal air cooling system that instantly solidifies strands after cutting, featuring precise temperature control for optimal results.
2.Designed for Film & Flexible Scrap
Benefit: Specializes in efficiently processing challenging, low-bulk-density materials like post-consumer film, agricultural film, and packaging scraps that are difficult for traditional systems.
Feature: Robust feeding and pre-conditioning system, paired with a high-torque extruder, ensures consistent melting and feeding of light, flexible materials.
3.High Efficiency & Energy Savings
Benefit: The dry process significantly reduces total energy consumption by removing water heating, pumping, and pellet drying stages, leading to lower operating costs.
Feature: Energy-optimized DC or EC motor drives on the extruder and high-efficiency blowers for the cooling system.
4.High-Quality, Contaminant-Free Pellets
Benefit: Produces uniform, dry, and clean pellets ready for immediate packaging or use in downstream manufacturing, free from water-borne contamination or moisture-related issues.
Feature: Precision die-face cutting technology with hardened blades and a closed-loop air system that filters fines for a superior final product.
5.Compact & Simplified Process Line
Benefit: Requires less floor space and infrastructure (no water tanks, dryers) than a water-ring system. The workflow is simpler, reducing maintenance points and operational complexity.
Feature: Plastic Granulating Line Integrated design from extruder to pellet collection silo, with a streamlined layout for easy access and operation.
