Three-Stage Plastic Pelletizing Line | High-Capacity & High-Purity Waste Plastic Recycling Pelletizing Solution
As a key national pilot city for the national waste recycling system, Linyi has built a complete industrial chain: Waste Resources → Collection Outlets → Sorting Centers → Processing Plants. The city processed 2.81 million tons of various waste materials in 2023, with surging demand for pelletizing waste paper pulp residue, woven sacks and snake-skin bags. As China’s major woven bag distribution hub, Linyi’s Lantian Woven Bag Market is the country’s largest specialized trading center with annual wholesale volume exceeding 2 billion pieces. Tancheng and Linshu Counties operate complete waste paper collection networks generating abundant waste pulp recycling demands. Local manufacturers commonly struggle with low pellet output and poor purity when processing high-moisture, high-impurity feedstock. Focused on domestic plastic recycling equipment R&D, Tenglong develops the Three-Stage Plastic Pelletizing Line matching local industrial and regulatory requirements, delivering one-stop high-yield high-purity recycling solutions for large-scale waste plastic processors in Linyi, southern Shandong and East China and supporting compliant eco-friendly production per circular economy regulations.
Three-Stage Plastic Pelletizing Line
1. Product Overview
The three-stage plastic pelletizing line is tailor-made for clients requiring large output and premium pellet quality, functioning as core processing gear for difficult-to-recycle feedstock including paper pulp scraps, woven sacks and snake-skin bags in Linyi. Benefiting from Hedong National Recycled Plastics Base’s cluster advantages and abundant raw materials supplied by Lantian Woven Bag Market plus Tancheng waste paper recycling base, the unit adopts triple melting & triple filtration technology. Raw material undergoes three cycles of thermal melting and impurity separation to produce dense, smooth pellets with drastically boosted productivity. Widely applicable for wet-state pelletizing of paper pulp residue, snake-skin bags and woven sacks, it excels at high-moisture high-impurity waste materials prevailing across Linyi. It helps enterprises build the “Resource-Product-Waste-Recycled Resource” circular chain and fulfills the core task of lifting comprehensive waste plastic utilization and cultivating large-scale processors defined in Linyi Waste Recycling System Implementation Plan.
2. Core Technical Advantages
Three-Stage Process Ensures High Purity & Large Output
Designed for Linyi’s typical high-impurity high-water-content feedstock (paper pulp scraps, woven bags, snake-skin sacks), triple heating melting plus triple filtration thoroughly removes paper fiber, silt and contaminants to greatly upgrade pellet purity. Pre-crushed and cleaned materials can go straight into wet pelletizing without extra crushing, hitting hourly output of 400–600kg/h to satisfy massive production at Hedong Recycled Plastics Base, raising factory yield and cutting material wastage.
Custom Screw & Premium Material for Outstanding Durability
Screws are forged from 38CrMoAl alloy steel after quenching, tempering and nitriding treatment for superior wear and corrosion resistance and extended service life, perfectly suited for long-hour heavy-duty processing of impurity-laden paper pulp and woven bag scraps. Optimized screw geometry delivers stable operation with minimal breakdown frequency for high-moisture dirty feedstock, supporting uninterrupted continuous production to cut maintenance and running cost as pursued by local Linyi recyclers.
Water-Cooled Strand Pelletizing for Uniform Good-Looking Pellets
Equipped with variable-frequency controlled water-ring strand cutting technology, the machine accurately regulates pellet dimension for uniform granules with smooth cutting surfaces, fully compliant with downstream manufacturing and commodity trading standards. Superior pellet appearance raises added value of recycled pellets for Linyi recyclers to access premium plastic weaving and injection molding buyers surrounding Lantian Woven Bag Market and strengthen product market competitiveness.
Strong Compatibility for Diversified Raw Materials
Optimized for mainstream local recycled feedstock (paper pulp residue, woven sacks, snake-skin bags), the line runs stably and maintains consistent pellet quality even with high moisture and heavy impurities without frequent parameter adjustment. Its versatile design adapts effortlessly to paper scrap recycling in Tancheng & Linshu and woven bag processing around Lantian Market, maximizing equipment utilization rate amid Linyi’s diverse waste plastic varieties.
