Plastic Recycling Pelletizing Line Delivered to African Client
Yongte Plastic Recycling Pelletizing Line Delivered to African Client
1. Project Overview
Recently, Yongte successfully completed the customized design, manufacturing and delivery of a full-set waste plastic recycling pelletizing production line for a professional plastic recycling enterprise in Africa. Driven by the booming local waste plastic recycling market and stricter requirements for recycled plastic pellet quality, the African client faced prominent production bottlenecks with their original conventional recycling equipment: excessive metal impurities and dust residues in finished plastic pellets, frequent equipment jamming caused by mixed impurities, unstable pellet quality and low production efficiency.
After in-depth communication about local waste plastic raw material characteristics, production site conditions and final product application demands, Yongte tailored an integrated high-precision impurity removal and pelletizing solution for the client. This customized production line features an innovative integrated crushing and vibrating screening machine matched with a dual-step plastic pelletizer equipped with an automatic hydraulic screen changer, realizing full-process automatic impurity separation and high-quality pellet production for waste plastics.
2. Customized Production Line Configuration & Core Process Flow
Yongte optimized the whole production process targeting the complex impurity characteristics of local African waste plastics (mixed with iron scraps, dust, sediment and other sundries), forming a seamless one-stop recycling workflow: Waste Plastic Feeding → Integrated Crushing & Vibrating Screening → High-purity Plastic Flakes Conveying → Dual-step Pelletizing → Automatic Hydraulic Screen Changing → High-quality Recycled Pellet Finished Products
2.1 Core Customized Equipment Highlights
2.1.1 Integrated Crushing and Vibrating Screening All-in-One Machine
Different from traditional separated crusher and screening machines that occupy large space and have low screening efficiency, Yongte adopted an integrated structural design for this project. The equipment firstly crushes bulk waste plastics into uniform plastic flakes with standard particle sizes through high-strength crushing blades. Immediately after crushing, the built-in high-frequency vibrating screening system operates synchronously to achieve layered separation of impurities:
- Heavy metal impurities such as iron fragments are screened and discharged separately through the bottom heavy impurity outlet;
- Light dust and fine sediment are removed completely via wind dust removal and vibration screening system;
- Only clean, impurity-free plastic flakes are transported to the next pelletizing procedure.
This integrated design saves 30% of the workshop floor area compared with split equipment, reduces intermediate material transfer links, and fundamentally avoids secondary mixing of impurities during transportation.
2.1.2 Dual-step Plastic Pelletizer
Matching the pre-purified plastic flakes, the dual-step pelletizing machine is adopted for staged melting and extrusion. The first stage completes preliminary plastic melting and further micro-impurity filtration, while the second stage realizes homogenization extrusion of molten plastic. This dual-stage heating and extrusion structure ensures thorough plastic melting, uniform melt viscosity, and effectively improves the density and surface smoothness of finished plastic pellets, avoiding defective products such as hollow pellets and uneven particle sizes caused by incomplete melting in single-stage pelletizers.
2.1.3 Automatic Hydraulic Screen Changer System
As a key quality guarantee module of the pelletizing line, the built-in automatic hydraulic screen changer supports non-stop online screen replacement. During long-term continuous production, residual tiny impurities that are not removed in the front screening process will be intercepted by the filter screen. When the screen is blocked, the system can automatically complete screen switching within 10 seconds without shutting down the production line. It eliminates manual screen changing downtime, avoids melt leakage risks caused by manual operation, and maintains stable extrusion pressure and consistent finished pellet quality all the time.
3. Client Feedback
“Local waste plastics are mixed with a lot of metal and dust impurities, and our old equipment could not solve the impurity removal problem thoroughly, leading to poor pellet quality and difficulty in selling products. Yongte's customized integrated crushing and screening machine solves our biggest pain point perfectly. The dual-step pelletizer runs stably, and the automatic screen changer saves us a lot of time and labor. The whole production line is tailored to our local raw material situation, easy to operate and maintain. We are very satisfied with Yongte's professional customization capability and after-sales technical support.”— Production Manager of African Plastic Recycling Client
4. Conclusion
This cooperation project once again proves Yongte's strong capability in targeted customized plastic recycling equipment. Facing different raw material conditions, site limitations and quality demands from global customers, Yongte does not adopt standardized general equipment blindly, but provides one-stop overall recycling solutions based on actual working conditions. In the future, Yongte will continue to focus on technological innovation of plastic recycling machinery, helping more global recycling enterprises realize efficient, low-cost and high-quality waste plastic regeneration production, and promote the development of global circular economy.
