Aluminum-plastic Recycling Machine for Blister Packs
The aluminum-plastic medical blister pack recycling machine utilizes physical crushing, micro-grinding, and high-voltage electrostatic separation technologies to efficiently separate pharmaceutical factory waste and post-consumer medical composite blister packs into high-purity aluminum powder and plastic powder, achieving sustainable resource recycling.
1. Core Process Flow: From Mechanical Crushing to High-Voltage Electrostatic Separation
This aluminum-plastic separation production line employs a purely physical sorting mechanism without relying on chemical reagents. The core processing workflow comprises the following four critical stages:
Coarse Crushing Stage: The composite aluminum-plastic raw materials first enter the knife crusher. Through the shearing action of high-strength blades, the materials are uniformly shredded into small pieces of approximately 10mm.
Micro-Grinding and Cooling: The coarsely crushed material then proceeds into the water-cooling turbo-type grinding machine. Within the high-speed rotating turbo flow field, the material is pulverized into fine powder. Since the grinding process generates friction heat, the system is equipped with a standard circulating water-cooling system to prevent the plastic from melting or denaturing due to overheating, thereby ensuring stable material properties.
Sieving and Closed-Loop Recirculation: The ground powder enters a rotary screen for particle size classification. Oversized particles that do not meet the size requirements are retained and returned to the grinding machine for secondary milling. Conversely, fine powders that meet the specifications are directly conveyed to the next processing stage.
High-Voltage Electrostatic Separation: The qualified micro-powder enters the electrostatic separator. Utilizing the distinct electrical conductivity differences between aluminum (conductor) and plastic (insulator) within an electric field, the equipment achieves precise trajectory separation of the two materials. Ultimately, high-purity aluminum powder and plastic powder are discharged separately at the output ends.
2. Technical Parameters: Performance Comparison Between APR-300 and APR-500
To satisfy the investment requirements of various production scales, SUNY GROUP has launched two standardized configurations. The specific technical parameters are detailed below:
| Model | Capacity(kg/h) | Power(kw) | Dimension(m) |
| APR-300 | 200-300 | 125 | 9*7*5 |
| APR-500 | 400-500 | 270 | 18*9.3*5 |
In practical equipment selection, clients must comprehensively evaluate workshop height constraints (both models require a ceiling height of 5 meters) and power allocation. While the APR-500 doubles the throughput capacity, its footprint and power consumption increase accordingly, making it highly suitable for large-scale centralized recycling centers.

3. Eco-Friendly Dust Collection: The Ecological Value of Physical Separation
Traditional aluminum-plastic separation methods often rely on chemical stripping or incineration, which not only damages the integrity of the metallic fibers but also generates hazardous gases. In contrast, this system strictly adheres to a "zero-chemical-addition" dry physical sorting route. To mitigate the dust inevitably generated during the milling process, the entire production line operates under sealed negative pressure and comes standard with a pulse dust collector.
This dust collection system efficiently captures micron-level ultra-fine dust. While recovering high-value airborne particles from the waste, it ensures that the discharged air meets strict clean air emissions standards. This systematic engineering design—integrating high-efficiency separation, water-cooled temperature control, and pulse dust collection—not only significantly elevates the recovery purity of the aluminum and plastic but also fully complies with stringent international environmental impact assessments (EIA) and industrial regulations.
