Circuit board crushing and separation equipment is a new type of environmental protection equipment specially developed for recycling waste circuit boards. It adopts dry physical separation method and realizes the separation of metal powder and resin fiber through two processing steps of crushing, screening, sorting, and dust removal. The separation rate of Henan Dongying’s circuit board crushing and separation equipment can reach more than 99%.

Next, I will introduce the working process of the circuit board crushing and separation equipment in detail: waste circuit boards are sent into the hammer crusher, and then into the hammer crusher for double crushing; the crushed materials enter the rotary vibrating screen, and the diameter is sufficient and qualified. The material enters the air flow specific gravity separator, and the material with unqualified diameter is sent back to the hammer crusher for secondary crushing; the material enters the air flow specific gravity separator for the first screening; after that, the material enters the electrostatic separator for secondary crushing. The second sorting; the pulse dust removal equipment is responsible for the whole process of dust removal.

The domestic production technology of circuit board crushing and separation equipment is very mature. While the sorting rate reaches 99%, the equipment also meets environmental protection emission standards. The circuit board crushing and separation equipment independently developed by Henan Dongying has also carried out a series of technical upgrades on this basis, such as the double crushing design of the hammer crusher and the hammer crusher, which can not only protect the equipment blade but also ensure that the circuit board is broken. Fully crushed; the self-developed pulse dust removal equipment can also provide a continuous and stable dust removal, even very fine dust can be easily removed, and the usable time is even longer than the common bag dust removal.
