Materials used by circuit board recycling equipment in mechanical processing technology

The material separation process of circuit board recycling equipment in mechanical treatment technology should be based on the monomer separation of each material. The difference in the degree of crushing will affect the energy consumption of the equipment, and will also directly affect the subsequent separation process.

Therefore, breaking is a very important link. In this process, commonly used crushing equipment mainly includes hammer mill, hammer mill and rotary crusher. Through the study of the crushing process, it was found that when the metal was crushed to 0.66 mm, separation could be achieved. The choice of crushing method and crushing equipment should be determined according to the subsequent process.

The sorting of circuit board recycling and processing equipment is mainly used in the sorting process of magnetic, electrical and material density of materials in waste circuit boards. Magnetic separation and electrical separation of waste circuit board materials can be separated by traditional magnetic separators, and electrostatic separators are also commonly used sorting equipment in the waste circuit board separation process.

Density separation technology uses the weight of different materials to separate after the metal material is decomposed. It should be noted that the metal material in the alloy state and the change in material weight have little effect on the sorting results. The equipment selected in the material density sorting process is a wind separator and a cyclone separator, but the stability of these two equipment is poor and is affected by the supply situation.
