recycling machinery for solar panels

Solar panel recycling production lines mainly include the following core equipment:

Disassembly equipment: used to separate aluminum frames, junction boxes and glass, usually using mechanical cutting or pyrolysis technology.

Crushing and sorting system: crush the components and classify them by material (silicon, metal, glass, plastic) through crushers, vibrating screens and airflow sorters.

Chemical purification device: extract high-purity silicon and precious metals such as silver and copper from silicon wafers by acid leaching or electrolysis.

Dust removal and exhaust gas treatment system: ensure that the recycling process meets environmental standards and avoids the leakage of harmful substances.

Production line workflow

Pretreatment: manually remove cables and aluminum frames to initially separate reusable components.

Crushing and sorting: after the components are crushed, metals and non-metallic materials are separated by magnetic separation, eddy current sorting and other technologies.

Chemical treatment: silicon wafers are acid-washed or heat-treated to purify silicon materials and recover precious metals such as silver paste.

Material recycling: Glass can be used for new components or building materials after cleaning, plastic particles can be used in the injection molding industry, and metals can be recycled.

Final products

After recycling, you can get:

High-purity silicon materials (for new photovoltaic cells or semiconductors)

Metals such as silver, copper, and aluminum (directly enter the metallurgical industry)

Crushed glass (for glass manufacturing or building materials)

Plastic particles (for industrial products)

Economic and environmental significance

Economic benefits: Recycling 1 ton of photovoltaic modules can extract metals and silicon materials worth about US$500-1,000, reducing the cost of raw materials.

Environmental value: Reduce landfill pollution, save mineral resources, and reduce carbon emissions by about 1.2 tons for every ton of modules recycled.

With the advent of the photovoltaic scrap wave, professional recycling equipment will become a key link in the green energy industry chain and promote the development of the circular economy.
