1. Project Overview\u00a0<\/b><\/h3>\n
    \n
  • \n

    Location:<\/b> Nigeria<\/p>\n<\/li>\n

  • \n

    Date:<\/b> May 2023<\/p>\n<\/li>\n

  • \n

    Material:<\/b> PP\/HDPE Rigid Plastics (Crushed sheets\/scraps)<\/p>\n<\/li>\n

  • \n

    Equipment:<\/b> 500kg\/h Double Stage Pelletizing Line (180mm)<\/p>\n<\/li>\n

  • \n

    Final Application:<\/b> Injection Molding Grade Pellets<\/p>\n<\/li>\n<\/ul>\n

    \n

    2. The Challenge\u00a0<\/b><\/h3>\n

    The client in Nigeria aimed to process 12 tons of waste rigid plastic per day<\/b> to produce high-quality industrial-grade pellets. Key requirements included:<\/p>\n

      \n
    • \n

      Consistent Quality:<\/b> Pellets must meet the rigorous standards for injection molding.<\/p>\n<\/li>\n

    • \n

      Space & Operation:<\/b> The equipment needed to be compact<\/b> to fit their existing facility and user-friendly<\/b> for local operators to manage with ease.<\/p>\n<\/li>\n

    • \n

      Durability:<\/b> The line had to withstand long hours of continuous operation in a demanding environment.<\/p>\n<\/li>\n<\/ul>\n

      \n

      3. Ruili Machinery\u2019s Solution\u00a0<\/b><\/h3>\n

      Our technical team engineered a Customized Double Stage Pelletizing System<\/b> specifically for rigid PP\/HDPE materials:<\/p>\n

        \n
      • \n

        Double-Stage Extrusion (180mm):<\/b> The two-stage design ensures superior degassing and double filtration, removing impurities and moisture to guarantee dense, bubble-free pellets.<\/p>\n<\/li>\n

      • \n

        Full Production Loop:<\/b> The line was fully integrated, including the Main & Vice Extruders, Cooling Water Tank, Noodle-type Cutting System, and Storage Silo<\/b>.<\/p>\n<\/li>\n

      • \n

        Compact Engineering:<\/b> Optimized the layout to minimize the footprint while maintaining high throughput.<\/p>\n<\/li>\n

      • \n

        Simplified Controls:<\/b> Designed for easy operation with a stable PLC system, reducing the learning curve for the site staff.<\/p>\n<\/li>\n<\/ul>\n

        \n

        4. Results & Performance\u00a0<\/b><\/h3>\n

        Since the installation in May 2023, the plant has achieved:<\/p>\n

          \n
        • \n

          Target Output:<\/b> Stable daily production of 12 tons, meeting the client\u2019s scaling goals.<\/p>\n<\/li>\n

        • \n

          Industrial-Grade Output:<\/b> The recycled pellets are now successfully used in the production of high-end injection molded products.<\/p>\n<\/li>\n

        • \n

          Reliability:<\/b> Zero operational failures<\/b> reported to date, showcasing the robust build quality of Ruili machinery.<\/p>\n<\/li>\n

        • \n

          Cost Efficiency:<\/b> Significant reduction in production costs compared to their previous manual or sub-standard processing methods.<\/p>\n<\/li>\n<\/ul>\n

          \n

          5. Customer Feedback\u00a0<\/b><\/h3>\n
          \n

          “Ruili\u2019s double-stage granulator transformed our recycling business. The 180mm system is powerful yet very easy to operate. We are now producing 12 tons of high-grade pellets every day without any downtime. Their engineering team truly understands the needs of the Nigerian market.”<\/i><\/p>\n
