Case Study: 300kg/h PP/HDPE Rigid Plastic Granulating System in Tanzania
1. Project Overview Location: Tanzania Date: October 2023 Material: PP/HDPE Rigid Plastics (Crushed industrial scraps) Equipment: 300kg/h Double Stage Pelletizing Line (150mm) Final Application: High-Quality Injection Molding 2. The Challenge A recycling startup in Tanzania needed a reliable solution to process 6 tons of rigid plastic waste daily. Their primary hurdles were: Quality Consistency: The recycled pellets needed to be pure enough for high-end injection molding applications. Operational Ease: As a growing facility, they required equipment that was easy to maintain and simple for local staff to operate without extensive technical training. Space Optimization: The production line needed to be compact to maximize the efficiency of their workshop layout. 3. Ruili Machinery’s Solution We provided a Customized 150mm Double Stage Pelletizing Line tailored for the Tanzanian market: Optimized Double-Stage Design: The 150mm main and vice extruder configuration ensures deep degassing and fine filtration, effectively removing impurities from rigid PP/HDPE scraps. Integrated Workflow: A seamless “Turnkey” setup including the Main & Vice Extruders, specialized Cooling Tank, precision Noodle Cutting system, and finished product Storage Silo. User-Centric Engineering: Focus on a simplified control interface and robust mechanical components to ensure long-term stability with minimal supervision. High ROI Design: Specifically engineered to provide
