Linia do recyklingu folii BOPP, zagęszczania i peletyzacji – uruchomienie próbne

Folie CPP (polipropylen odlewany) i BOPP (polipropylen dwuosiowo orientowany) to wysokowydajne materiały plastikowe szeroko stosowane w opakowaniach żywności, taśmach klejących, podłożach drukarskich i innych dziedzinach. Wraz ze wzrostem zapotrzebowania na ochronę środowiska, efektywny recykling i ponowne wykorzystanie ich odpadów foliowych stały się kluczowym celem w branży. Ta linia produkcyjna została specjalnie zaprojektowana do recyklingu, zagęszczania i peletyzacji folii CPP/BOPP. Poprzez procesy takie jak kruszenie, czyszczenie, zagęszczanie i wytłaczanie w stanie stopionym, odpadowe folie są przekształcane w wysokiej czystości granulki z recyklingowanego plastiku, co pozwala na recykling zasobów i redukcję zanieczyszczenia środowiska.

Core Components

Crushing and Pre-treatment System

• Powerful Crusher: Adopts a dual-axis shear design for efficient crushing into flake-shaped particles, suitable for high-toughness films.
• Podkładka cierna: Removes surface inks, adhesives, and impurities through high-speed water flow and mechanical friction.
• Centrifugal Dewatering + Hot Air Drying: Multi-stage dewatering ensures low moisture content (≤1%) of the material, ensuring stability for subsequent processing.

Compaction and Melting System

• Spiral Compactor: Compresses loose films into high-density blocks under high temperature and pressure, reducing volume and pre-removing volatiles, thus improving melt efficiency.
• Forced Feeding Device: Ensures uniform feeding into the extruder, preventing bridge blockages.

Extrusion and Pelletizing System

• Two-stage Extruder:
• First Stage Melt Extrusion: Equipped with a high-torque screw, low-temperature shear plasticization reduces thermal degradation.
• Second Stage Filtration and Venting: Multi-layer filter mesh (automatic screen changer) removes micro-impurities, and vacuum venting removes residual volatiles.
• Underwater Pelletizer: Produces uniform pellets with a diameter of 3-5mm. After cooling, the pellets have low moisture content and can be directly used for downstream production.

Inteligentny system sterowania

• PLC + Touchscreen Integrated Control: Monitors parameters such as temperature, pressure, and speed in real-time, supporting data storage and fault diagnosis.
• Energy-saving Mode: Automatically adjusts energy consumption to reduce operational costs.

Technical Advantages

• High Compatibility: Compatible with CPP, BOPP, PE, and other soft plastic films, and supports materials with printed/composite layers.
• Low Loss Rate: Closed-loop water circulation system + efficient filtration, with a raw material recovery rate of ≥95% and pellet purity of over 98%.
• Energy-saving and Environmentally Friendly: Heat recovery design reduces energy consumption; exhaust gases are treated with activated carbon adsorption, meeting environmental emission standards.
• Flexible Capacity: Modular design supports customized configurations, with a production capacity range of 500-2000kg/h, meeting different scale needs.
