PE-Coated Aluminum Recycling Line
PE-coated aluminum materials are widely used in packaging, building materials, decorative panels, and other fields due to their lightweight, corrosion resistance, and excellent formability. With the development of green manufacturing and the circular economy, achieving efficient separation and recycling of the PE layer from the aluminum substrate has become a key focus for the industry. This article will introduce a comprehensive and feasible PE-coated aluminum recycling technology solution and key equipment, providing a reference for enterprises.
Overall Process and Technical Principles
PE-Coated Aluminum Recycling Line
The objective of this recycling production line is to efficiently remove PE and obtain high-purity aluminum powder. The typical process flow includes: feeding → crushing → grinding → electrostatic separation → collection → post-processing. Through mechanical crushing and grinding, the PE-coated aluminum material is progressively refined. Electrostatic separation equipment is then used to precisely separate aluminum powder from PE powder based on their differing conductivity. The entire process is highly automated, supplemented by dust collection systems and intelligent conveying devices to ensure clean, safe, and stable operation.
Core Equipment and Technical Advantages
In the crushing stage, dual-shaft or single-shaft crushers are used to reduce large materials to an appropriate particle size. The key points of the equipment lie in the blade material and wear resistance to ensure continuous operation and low maintenance costs. During the grinding stage, high-speed rotation combined with a negative pressure system effectively prevents dust leakage; simultaneously, temperature control and screening systems are equipped to prevent PE from melting and adhering while precisely controlling powder particle size. The electrostatic separator, as the core equipment, utilizes the principle of charged particles deflecting in an electric field to efficiently separate aluminum and PE, achieving a separation accuracy of over 98%, with low energy consumption and no water pollution. Finally, through the finished product collection device, high-purity aluminum powder and PE powder are obtained separately, achieving resource reuse.
In terms of auxiliary equipment, the comprehensive dust removal and conveying systems not only enhance production continuity and safety but also pave the way for future automation upgrades. Feedback from some users indicates that this production line excels in terms of production capacity, recovery rate, and maintenance costs, helping enterprises quickly recoup investments and enhance environmental competitiveness. For users with such needs, introducing or upgrading such production lines not only improves resource utilization efficiency but also brings significant economic benefits.
