PV Module Disassembly Crushing and Sorting Line

This PV module disassembly, crushing and sorting line utilises a combination of physical and thermal processes to efficiently separate the aluminium frames, junction boxes and high-purity glass from solar panels, whilst precisely sorting out metals such as copper and silicon powder. It is a key piece of equipment for achieving the recycling of PV materials.

Automated Front-End Disassembly: Efficient Stripping of Frames and Glass

The primary stage in PV module recycling is the complete separation of the outer casing from the encapsulation materials. The semi-automatic frame and junction box disassembly machine included in this solution enables a ‘one-step’ process for simultaneously removing the aluminium frame and junction box. As it utilises manual loading, the equipment offers exceptional operational flexibility for solar panels within a specific size range.

The subsequent heated adhesive removal and glass peeling machine is central to enhancing material purity. It utilises precise temperature control technology to weaken the adhesive properties of the EVA layer, enabling the tempered glass to peel off in uniform, granular chunks. This not only significantly improves the recovery rate of glass but also prevents glass debris from contaminating the subsequent cell stream, thereby ensuring the recycling value of the downstream materials.

Refined Mid-to-Late Stage Sorting: Pure Extraction of Non-ferrous Metals and Silicon Powder

After the protective layer has been removed, the solar cells enter the cell crushing and sorting line for in-depth resource recovery. The system refines the material through multi-stage crushing and employs a combination of physical processes such as air-classification and electrostatic separation.

The key technology of this production line lies in its precision separation capabilities, enabling the high-purity enrichment of valuable non-ferrous metals—such as copper and aluminium powders—from non-metallic resins and mixed silicon powder. This multi-stage sorting process circumvents the environmental pressures associated with chemical methods, ensuring the recovery efficiency of core precious metals like copper through a low-energy, high-output physical sorting model.

It not only achieves a closed-loop recycling process for photovoltaic modules—from dismantling the casings to extracting the internal metals—but also facilitates industrial-scale PV processing that balances economic benefits with environmental standards.
