With PCB industrialization, large-scale, and wide application of electronic products, more electronics are produced and manufactured in the production and life activities of human society.
The waste contains lead, mercury, hexavalent chromium, etc., PCB also contains harmful substances, and contains toxic substances such as polybrominated biphenyls (PBB), polydibenzaldehyde (PBDE) and other chemical substances, which organically contaminate soil and water Resources cause human health, and also cause wasted resources, which are then recycled. There are nearly 20 kinds of scrap PCB non-ferrous metals and rare metals, which have economic value of recyclability.
Therefore, it is very important to properly dispose of used PCB circuit boards.
Methods of using our machines to dispose of electronic waste:
1.1 Crushing
Mechanically crush PCB, disintegrate and separate the metal and organic matter, and improve the sorting efficiency. When the crushed particles reach 0.6mm, the metal can basically reach 100% dissociation, but the choice of crushing method and grade depends on the subsequent process.
1.2 Sorting
According to the difference in physical properties such as density, particle size, conductivity, magnetic permeability and surface characteristics of the crushed materials, it can be carried out by wind shaker technology, flotation separation technology, cyclone separation technology, float-sink separation and eddy current separation technology, etc. sorting.
