Dirty Film Washing & Pelletizing Line | One-Stop Recycling & Pelletizing Solution for Dirty Contaminated Plastic Films
As a national key pilot city for waste circular economy construction, Linyi boasts complete waste recycling network and massive annual recovery volume hitting 2.81 million tons in 2022. Agricultural mulch, greenhouse film and contaminated packaging film recycling sees explosive market demand. Being a major agricultural city in Shandong, Linyi consumes tremendous plastic films for farming; discarded dirty films carry heavy mud and grease contaminants and pose major processing challenges for local recyclers. Tenglong develops the Dirty Film Crushing Washing Pelletizing Line matching local industrial trends and government policies, delivering integrated one-stop solution for contaminated film recycling and pelletizing for film recyclers in Linyi, southern Shandong and East China, helping factories operate efficiently, legally and eco-friendly under circular economy regulations.
Dirty Film Crushing Washing Pelletizing Line
1. Product Overview
The Tenglong Dirty Film Crushing Washing Pelletizing Line is tailor-made one-stop recycling equipment for contaminated agricultural mulch, greenhouse film and used packaging film, the key production gear helping local recyclers tackle tough dirty feedstock processing issues. Supported by Linyi’s full-coverage waste recycling network and Hedong National Recycled Plastics Industrial Cluster, the production line innovatively integrates crushing, cleaning and wet pelletizing. Pre-crushed and cleaned films go straight into pelletizing without intermediate transfer. Equipped with horizontal forced feeding and electromagnetic heating technology, it efficiently removes residual moisture and volatile impurities to produce uniform pellets with low material loss and high yield, applicable for both agricultural waste film and industrial dirty packaging film recycling. It facilitates enterprises to build the circular economy loop: Resources → Finished Goods → Waste → Recycled Raw Materials, fulfilling the core target of improving comprehensive waste plastic utilization specified in Linyi Waste Recycling System Implementation Plan.
2. Core Technical Advantages
One-Stop Integrated Flow for Direct Wet Pelletizing of Dirty Films
Dirty agricultural & greenhouse films loaded with mud and grease require tedious multi-step pre-treatment on conventional production lines. This integrated line enables direct wet pelletizing post crushing and cleaning without independent drying procedure, greatly shortening workflow, cutting power and labor cost and eliminating repeated intermediate handling. It satisfies intensive large-scale production requirements of Hedong recycled plastics base and effectively lowers manufacturers’ operating expense.
Forced Feeding + Electromagnetic Heating for Remarkable Energy Saving
Horizontal forced feeder with honeycomb drainage holes drains excess water out of wet films efficiently. Matched with high-speed, energy-saving electromagnetic heating system cutting over 20% power consumption versus traditional heating modes, the unit removes moisture and volatile contaminants thoroughly and achieves adjustable output ranging from 250–500kg/h. The energy-efficient design complies with Linyi’s environmental supervision standards and national dual-carbon goals and enables factories to enjoy preferential taxation policies for comprehensive resource utilization.
High-Efficiency Degassing & Purification for High-Purity Recycled Pellets
Specially optimized screw structure plus independent exhaust vents eliminate entrapped moisture and volatile contaminants completely to avoid bubble formation and smoking during wet plastic extrusion, upgrading pellet purity, density and surface quality to satisfy downstream manufacturing standards. As benchmark equipment among PE film crushing washing pelletizing lines, superior granule quality raises added value of recycled pellets for Linyi recyclers to access high-end downstream buyers and lift market competitiveness in line with Linyi’s circular economy upgrade guideline and national waste plastic utilization compliance standards.
High Automation & Stable Continuous Operation
Full-linked automated production minimizes manual intervention and solves local recyclers’ labor shortage and high manpower cost difficulties. Optimized for all types of contaminated PE agricultural films widely collected in Linyi, the machine runs stably with low failure rate for non-stop mass production at Hedong recycled plastics base and avoids production loss caused by unexpected shutdown.
