How Blister Packaging Separators Recover 99% Pure Aluminum

Aluminum-plastic separation equipment is a fully dry, physical sorting system designed to efficiently process composite waste—such as pharmaceutical blister packs—into high-purity aluminum powder and plastic. By completely eliminating the need for chemical solvents, the system transforms low-value waste into high-value, dual-stream material outputs.

Core Process: Purely Physical Shredding and Electrostatic Separation

The system relies exclusively on physical processes. First, a shredder reduces whole aluminum-plastic blister packs into fragments approximately 10 mm in size. These fragments then enter a pulverizer, where they are ground into a uniform, fine powder (20–40 mesh). Finally, the powder passes through a high-voltage electrostatic separator. Leveraging the difference in electrical conductivity between aluminum and plastic, the system imparts opposite electrical charges to the materials within an electric field, enabling precise separation based on their distinct physical trajectories.

Key Performance Metrics and Temperature Control

Under standard operating conditions, the equipment achieves an aluminum recovery rate of up to 99.5% and a plastic separation purity exceeding 99%. A critical operational detail is the inclusion of a circulating water-cooling system for the high-speed pulverization stage. Because the plastic components in blister packs are prone to heating and melting under mechanical friction, this cooling system prevents temperature spikes within the grinding chamber, ensuring the materials do not fuse together and maintaining high output purity during continuous operation.

Economic Benefits and Environmental Compliance

The resulting clean aluminum powder and plastic granules can be sold directly as industrial raw materials. Since recycled aluminum consumes approximately 95% less energy than aluminum produced from virgin ore—and because the system’s fully dry process generates zero wastewater and zero exhaust emissions—it offers a short return on investment (ROI). Furthermore, its operational performance easily meets the stringent environmental regulatory standards found in various global jurisdictions, providing a robust, fact-based foundation for SEO strategies focused on environmental technology.

Conclusion: With its distinct advantages of low energy consumption and zero pollution, modern aluminum-plastic separation equipment has emerged as the optimal mechanical solution for processing aluminum-plastic composite solid waste and achieving a closed-loop resource cycle.
