Solar panel recycling equipment mainly includes three parts: frame removal machine, glass removal machine, solar panel crushing and sorting equipment, the processing flow includes three stages:
Aluminium frame removal: use the frame removal machine to remove non-recyclable parts, such as aluminium side frames and junction boxes. Then the remaining panels are ready for subsequent recycling.
Glass removal: A glass removal machine is used to remove most of the glass from the surface of the old solar panels.
Shredding and sorting: The pre-processed panels are put into a shredder, shredded and then into a crusher, where the material is crushed into 1-2cm chunks. Through negative pressure feeding, these small pieces will enter the grinding machine. If the size of the milled material is not qualified, it will return to the mill for further grinding. The size-qualified material enters the airflow sorter, which screens out metal powder on one side and plastic and a small amount of metal on the other side. These plastics and a small amount of metal enter the electrostatic separator to separate the plastics from the metal. Finally, the different types of products are screened and sorted, including glass, copper, silicon and plastics.
