The mechanical crushing method for separating and recycling waste photovoltaic panel equipment mainly relies on physical cutting, hammering, extrusion and grinding to break the solar cells into smaller particles. Then, the particles of different sizes are screened and sorted, and the components containing EVA adhesive are heat treated to achieve the purpose of recycling glass, silicon and metal. The particle size of the particles after crushing by the rotor crusher is 0.08~8.00 mm, and then they are screened using a screen. Components with a particle size of more than 1 mm usually contain EVA, so it is necessary to heat treat the components with larger particle sizes once at 650 ℃. The smaller particle size is generally glass, silicon and metal. Glass is concentrated in the component with a particle size of 0.4~1.0 mm, and the metal component particle size is concentrated in 0.08~0.40 mm. The production line of monocrystalline silicon photovoltaic panel recycling and disassembly equipment promotes the photovoltaic module recycling industry towards large-scale, green and industrial development, extending and improving the photovoltaic industry chain.
