Product Overview

The dose feeding pelletizing line is designed for stable and accurate feeding of irregular rigid flakes/lumps and densified soft materials, supporting continuous pellet production for recycling plants and compounders.
It is widely used for HDPE / LDPE / PP recycling pellets, and can also handle densified film, woven bags, raffia, foam and other pre-treated materials with a dose feeder on the feeding inlet.

Key Advantages

Adjustable feeding speed helps maintain stable output for different material shapes and bulk density.
Integrated process design supports lower material loss (target: ≤2%) and consistent pellet quality through synchronized control.
Cutting options available: die-face / water-ring cutting or strand cutting (model-dependent).

Suitable Materials

HDPE bottles & rigid scraps, PP rigid regrind, pre-crushed pipes/containers/lumps; densified PE film, PP raffia, PE/PP woven, PE foam and similar pre-agglomerated feedstock.

Core Components & Configuration

Introduction

Dosing System

Feeds raw material into the extruder under controlled conditions.
Ensures consistent and stable material supply.
Extruder

Melts and plasticizes material through controlled heat and shear force.
Provides stable melt flow for pelletizing.
Water Ring Cutting Machine

Cuts molten strands into pellets at the die face.
Water ring stabilizes cutting and removes heat.
Dewater Machine

Removes excess water from pellets through mechanical dewatering.
Reduces moisture before final drying.
Vibrating Screen

Separates oversized and fine particles from finished pellets.
Improves pellet size uniformity.
Silo

Stores finished pellets in a stable condition.
Supports continuous transfer to packaging.

Applications & Production Scenarios

Applications

Plastic Raw Material Production: Produces PP/PE/PVC pellets (reference: ISO 1873-1) for injection molding, extrusion and blow molding, helping downstream processes keep stable pellet size and density.
Recycled Plastic Processing: Turns film/pipes/bottles scraps into pellets with recycling efficiency up to 98%; melt filtration with 120-mesh filter helps remove impurities (dust/metal particles) and improve pellet purity.
Masterbatch Production: Supports color masterbatch (pigment content 10–50%) and functional masterbatch; additive dispersion degree target ≥95% to reduce color streaks and performance inconsistency.

Output Pellet Use

Pellets can be used for granulation compounding, injection molding feedstock, extrusion-grade materials, and recycled pellet supply chains, depending on formulation and filtration configuration.
