HDPE Hard Material Granulator Project Overview The HDPE hard material granulator occupies a pivotal position in the plastic processing industry and is a key piece of equipment for the recycling and processing of HDPE hard materials. Rayli Machinery has rich experience in providing customized granulating solutions for global clients. Here is our successful 500kg/h HDPE hard flake granulator project in Côte d’Ivoire. Project Information Project Date: April 16, 2025 Location: Côte d’Ivoire Capacity: 500 kg/h Model: 160mm + 140mm Granulator Processed Material: HDPE hard flakes Customer Requirements & Solution The client in Côte d’Ivoire required a stable, high-efficiency granulator to process HDPE hard plastic flakes, aiming to convert waste HDPE into high-quality regrind pellets for reuse in local plastic manufacturing. After analyzing their material characteristics and production targets, our team recommended the 160mm+140mm dual-stage granulator system. The solution combines high-torque cutting technology with optimized rotor design, ensuring consistent 10-12mm granule size, low power consumption, and minimal downtime. It is fully adapted to the local power supply and harsh working environment. Equipment Features & Working Principle Our HDPE hard material granulator is designed for the recycling and processing of HDPE hard materials. Its working principle mainly covers processes such as material

Our 2000KG/H PE washing line is designed for HDPE irrigation pipe recycling, turning contaminated raw materials into clean scraps for high-quality granulation. Project Overview Location: Local Market Commission Date: March 2026 Capacity: 2,000 KG/H Material: HDPE Irrigation Pipes Application: PSF Fillings, Quilts& Paddling Customer Needs: Need to process 3T raw materials and get the output of 2T/h scraps and thus do granulation for high quality pellets. Solution: One process of Dry Friction Wash (getting rid of the mud, dirt and sand) + Two processes of Wet Friction Wash + Three big washing tanks.     Customer Needs & Challenges The customer’s core goal was to process 3 tons of raw contaminated PE irrigation drip tapes per hour, achieving a stable output of 2 tons of clean scraps. These scraps would then be granulated into high-quality HDPE pellets for non-woven fabric production. The main challenges included: 1. Heavy contamination (mud, sand, fertilizer residues) on the drip tapes 2. Large, folded bundles that are difficult to wash directly 3. Strict quality requirements for recycled pellets to meet Grade A standards Customized PE Washing Line Solution Rayli Machinery designed a multi-stage washing system to solve these pain points: – 1 stage of Dry

1. Project Overview Location: Malaysia Date: August 22, 2025 Capacity: 2000kg/h Material: Imported & Local HDPE Rigid Plastics Application: Premium Flakes for Injection Molding & Industrial Piping 2. The Challenge  The client, a licensed SME recycler in Malaysia, faced a dual challenge: Strict Compliance: Malaysia’s environmental policies require imported plastic waste to be processed with high efficiency and zero pollution leakage. Complex Feedstock: The mixed raw materials (local and imported) contained metal contaminants and non-plastic debris, requiring high-precision sorting to meet the quality standards of downstream pipe manufacturers. Consistency: They needed to balance high cleanliness with a stable 2-ton-per-hour throughput to maintain their manufacturing license quotas. 3. Ruili Machinery’s Solution  We designed a comprehensive, multi-stage cleaning and sorting plant focused on purity and automated separation: Advanced Pre-treatment: Integrated a Magnetic Separator and Eddy Current Separator to automatically remove ferrous and non-ferrous metals, ensuring the safety of downstream blades and the purity of the final flakes. Professional Cleansing: Utilized a Constant Temperature Hot Alkaline Solution Tank combined with high-speed friction cleaners to strip away stubborn labels, industrial oils, and glue. Density Separation: A precision flotation/sinking tank was used to isolate clean HDPE from other floating or sinking contaminants. Efficient Drying: A

1. Project Overview  Location: Central China Date: December 12, 2024 Equipment: 3000kg/h High-Efficiency HDPE Rigid Plastic Washing Line Input Material: Mixed HDPE waste from township collection centers Final Application: High-Purity Sheets for Melt Granulation 2. The Challenge  A regional recycling center was struggling with outdated equipment that could only achieve 85% purity. This led to: Low Market Value: The contaminated flakes sold for much lower prices. Narrow Profit Margins: High processing costs combined with low-quality output made the business unsustainable. Scaling Bottleneck: They needed a much higher throughput (3 tons per hour) to handle the growing volume of local HDPE waste. 3. Ruili Machinery’s Solution We implemented a state-of-the-art washing technology tailored for mixed rigid plastics, utilizing a 5-step optimized process: Pre-treatment: Automatic sorting and size reduction to prepare the material. Hot Alkaline Washing: Specialized high-temperature alkaline solution to dissolve stubborn organic fats and oils. High-Speed Friction Cleaning: Mechanically removing labels, glue, and surface contaminants. Flotation & Sedimentation: Advanced density separation to ensure 100% removal of non-HDPE sinkable impurities. Centrifugal Dehydration & Drying: Ensuring the final product is dry and ready for immediate extrusion.   4. Results & Performance  After the implementation of the Ruili 3000kg/h line, the results were
