working principle
Add the waste PE film into the PE film extrusion and cutting machine, and after a series of process steps such as pre crushing, pre washing, fine crushing, high-speed centrifugal cleaning, high-pressure underwater cleaning, dehydration, and drying, it is then cut into granules through the cutting system. Finally, recycled plastic pellets are obtained through a cooling system.
Technical Features
1. Wide applicability: Suitable for processing various types of films and PP woven bags with sediment content up to 80%.
2. Circulating water system: Adopting a circulating water system not only ensures the cleaning effect, but also controls the water flow and evaporation volume, saving energy and environmental protection.
3. Wear resistant design: The core part of the pre-processing module adopts wear-resistant design to ensure that the system can operate continuously for a long time and reduce maintenance costs.
4. Efficient removal of impurities: Pre crushing and pre washing systems can efficiently remove most impurities such as sediment, protect subsequent equipment, and significantly improve the service life of fine crushing and cleaning systems.
5. Fine crushing system: Targeted design, uniform film size after crushing, easy to clean.
6. High speed centrifugal cleaning: Apply corresponding blade impact force to different materials at a suitable rotational speed to achieve cleaning effect.
7. Strong pressure underwater cleaning: The cleaning tank drum is designed for strong pressure underwater cleaning, which can remove residual impurities to the maximum extent possible. Claw type uniform discharge ensures uniform discharge while controlling moisture content, providing a process foundation for the dehydration module.
8. Thin film drying technology: a thin film drying technology combining centrifugal dehydration, screw extrusion drying, and high-temperature hot air, which strictly controls the moisture content of the finished product within 5%, suitable for high-quality granulation requirements.
9. Mechanical operation optimization: Through theoretical calculations and multiple measurements, adjustments are made to the mechanical operation details of the crushing, cleaning, and drying processes to avoid losses caused by excessive material processing.
10. Automation control: The entire production line is automated, and the various units of the system operate in a correlated manner. It has a predictive function for possible abnormal situations while achieving high production capacity, ensuring system safety.
11. Can be equipped with granulation system: According to production requirements, corresponding granulation systems can be equipped to achieve integrated production.
