Description
The components in a solar panel consist of good quality glass, aluminium frames, plastic, silicon, mixed metal (used for the printed conductors on each cell), all of which (≥95%), can be successfully recycled by Mingxin Solar Panel Recycling Plant
Recycling Processing
1. Aluminum And J-Box Removal
The junction box of the PV panel as well as the surrounding aluminum bezel are removed from the solar panel using an automated framing machine. This step makes the subsequent handling process more efficient and reduces the need for manual handling.
2. Glass Removal
After the softening process, the PV panels are transported to the head section of the machine. At the headstock location, there are two rollers, and the PV glass panels are fed into the center of the rollers and squeezed to move forward.
At the same time, the glass panels are mechanically broken and separated by means of a knife (left-right reciprocating motion). The separated glass portion flows downwards at the exit and is collected and processed manually, while the glass panes are sent out above and again collected manually.
The material enters into the shredder through the conveyor, the two shafts are equipped with staggered blades, the two knife shafts in the process of rotating in opposite directions to achieve crushing through the shear of the knife blade as well as the tear of the knife teeth, crushing the raw material into smaller pieces, and sending it to the next shredder through belt conveyor. The output size of the shredder is 3-4 cm.
Granulator
Through the conveyor will be shredded materials into the crusher, the crusher is composed of blades and through the blade disk, through the rapid rotation of the blade hit the broken material will be further broken up and crushed, to facilitate the subsequent vibration screening process. Crushed material through the negative pressure air system into the next process. The pulverizer is equipped with sieve mesh aperture of 2.8 mm.
Vibratory Screen
The heavier material collected by the analyzer falls into the inlet of the grading screen, and the material with the required granularity through screening enters the specific gravity sorter for the next step, and the granularity not meeting the requirements is sent to the next process of grinding machine for further grinding. Grading screen is a layer of screen, screen aperture of 10 mesh-20 mesh.
Hammer Mill
The materials not meeting the requirements of granularity separated by the grading sieve are further ground by the grinder and flow into the collector through the induced draft fan for subsequent processing.
Gravity Separator
The materials meeting the requirements of granularity after grinding by the mill and screening by the grading sieve enter the specific gravity sorting machine for sorting and processing again respectively, of which the front outlet is the heavier metal powder, and the rear outlet is the lighter mixed powder of metal and plastic.
Electrostatic Separator
The mixture sorted out at the back end of the specific gravity sorting machine is fed into the high voltage electrostatic sorting machine through the spiral reamer and bucket elevator, in which the resin powder and copper powder are subjected to the final sorting process to get the resin powder and copper powder.
Pulse Dust Collector
The raised dust and ultra-fine dust produced in the operation of the whole set of equipment will be collected and discharged under negative pressure for treatment.
