Usually the service life of solar photovoltaic panels is about 20-30 years, according to statistics, by 2050 the number of end-of-life photovoltaic panels will be tens of millions of tons, such a huge amount, from the starting point of the circular economy to consider, the recycling of end-of-life photovoltaic panels, in order to achieve the green photovoltaic panels from the source to the end of the environmental protection. So how should the end-of-life photovoltaic panels be recycled?
A typical crystalline silicon solar PV panel consists of 65-75% glass, 10-15% aluminium frame, 10% plastic and 3-5% silicon. Recycling is the sorting and reuse of these materials in three main steps: first the PV panel module is dismantled, then it is shredded and finally the valuable metals in the PV panel are extracted by pyrolysis.
Shredding as an important part of the recycling process, the photovoltaic panels are first shredded to facilitate the next step of recycling and sorting. Usually choose double-shaft shear shredder to shred photovoltaic panels, the use of two relatively rotating shafts to form a shear, tearing shredding effect on the material, the equipment is designed with low speed, high torque, greater shear force, strong shredding power, better shredding effect, can be larger materials once cut to a smaller size, high stability, low noise.
