Mechanical treatment process of circuit board recycling equipment

The mechanical treatment process and sorting technology of circuit board recycling equipment realize metal recovery according to the difference in physical properties of each component in waste circuit boards. The purpose of crushing is to dissociate the metal in waste circuit boards as much as possible, so as to improve the separation efficiency. Shredding is also often a pretreatment technique for other recycling methods. , Generally, the metal can basically be dissociated when crushed to 0.6mm, but the choice of crushing method and series depends on the follow-up process.

The waste circuit board recycling process adopts two-stage crushing technology, using a shear crusher and a special grinder with shearing and impact effects respectively, which can grind the waste board into pieces of about 0.1-0.3mm; In the crushing stage, use a rotary cutter to cut the waste boards into 2cm×2cm pieces, and then send them to a hammer mill to grind them into fine particles.

Circuit board recycling equipment adopts physical methods for recycling, that is, the circuit board is mechanically crushed, and the metal and non-metal materials in the circuit board are separated, and then the process technology is sorted to obtain metal and non-metal, so as to realize the recovery of metal resources. method. The physical method of recycling circuit boards has the characteristics of less impact on the environment, and the amount of waste household appliances is also increasing. A large number of waste circuit boards will be produced in the dismantling of waste household appliances.
