Dongying waste circuit board recycling equipment is mainly used to separate metal and non-metal in waste circuit boards, copper clad laminates, circuit boards and scraps and other materials. The waste circuit board recycling equipment adopts the dry physical separation process, which is an environmentally friendly circuit board recycling equipment. The following introduces the process flow of the waste circuit board recycling equipment:

1. The waste circuit board enters the shredder through the conveyor belt for shredding. The circuit board is shredded into 3-5 cm pieces, and then enters the belt conveyor. The magnetic separator on the conveyor separates the iron in the material. After being selected, the remaining materials enter the crusher through the conveyor for crushing, making it a mixture of metal and resin fiber powder.

2. The crushed mixed material will enter the rotary vibrating screening machine for screening, and the circuit board mixed material that meets the required mesh number will enter the next link, and the mixed material that does not meet the requirements will return to the crusher for re-crushing and then enter the screening link . The mixed material that reaches the required mesh enters the air flow specific gravity separator, and according to the different specific gravity of metal and resin fiber powder, the air flow generated under the equipment is used for self-circulation to separate.

3. A small part of the metal may not be cleanly separated in the airflow separator because the proportion is similar to that of the resin fiber powder due to the crushing too finely, so this part of the material will be sent to the high-voltage electrostatic separator by the wind feeder. Using the conductivity of the metal to separate again, a metal separation rate of 99% is achieved.
