As the global plastic recycling industry moves toward efficiency and safety, agglomerators—critical for converting light plastic waste into high-density recyclable pellets—require reliable technical design and safety alignment. Langbo’s agglomerator series, focused on industrial applicability, integrates core technical advantages while meeting universal safety requirements, catering to the practical needs of recycling enterprises.
1. Core Technical Principles
Langbo’s agglomerators adopt a friction-heating integrated process, optimized for handling light plastic waste such as agricultural films and packaging scraps:
- Feeding & Mixing: Equipped with a variable-frequency conveyor and dual-screw pre-feeder, ensuring uniform feeding without material bridging or accumulation.
- Friction Heating: High-hardness alloy steel paddles generate heat through friction between components and materials, with precise temperature control to avoid over-melting or incomplete fusion.
- Pellet Forming & Cooling: Melted material is formed into pellets via mechanical shearing, followed by a water mist cooling system and dewatering screen to ensure stable pellet quality.
The equipment balances processing efficiency and pellet density, adapting to common recyclable plastics like PE, PP, and PVC.
2. Safety-Centric Design
Prioritizing operational safety, Langbo’s agglomerators integrate key safety requirements for industrial equipment:
- Feeding Port Protection: A grid guard linked to the main power supply via electromagnetic interlock, shutting down the system immediately if the guard is opened. Heat-insulating baffles are added for hot agglomeration models to prevent scalding.
- Mechanical & Temperature Safety: High-strength fasteners secure critical components, with torque limiters to protect the motor and paddles from overload. The temperature control system features double alarms and automatic shutdown to avoid overheating.
- Emergency Controls: Easily accessible emergency stop buttons at key operation positions, paired with bilingual operation manuals emphasizing pre-shift safety training.
3. Maintenance & Material Adaptability
Focused on long-term operational needs, the equipment features user-friendly designs:
- Modular Structure: Key components such as paddles and liners are quick to disassemble and replace, reducing maintenance time and costs. Wear-resistant materials extend the service life of core parts.
- Material Versatility: By adjusting paddle types and temperature settings, the equipment can handle a range of plastics—including PE, PP, EVA, and PET fiber—with stable pellet forming performance.
4. Field Application Performance
In practical applications with plastic recycling enterprises, Langbo’s agglomerators have demonstrated reliable performance: adapting to various light plastic waste, producing high-quality recyclable pellets, and meeting universal industrial safety and quality standards. The equipment balances efficiency, safety, and cost-effectiveness for recycling operations.
Langbo’s agglomerator development focuses on technical practicality and user needs, offering customized consulting and configuration services for enterprises with special material or production line integration requirements.
