Recycling waste circuit boards by physical crushing and sorting method


The circuit board metal recycling equipment uses the physical crushing separation method. The separation method all adopts the physical dry recycling process. After the circuit board is detinned, it enters the first crushing device, and the crushed material enters the second crushing system through magnetic separation. After the secondary crushing, the particle size is less than 3mm, which separates the metal and non-metal of the circuit board. After the secondary crushing material enters the negative pressure device, the non-metal powder is drawn out.

The heavier materials enter the specific gravity separation system to separate the metallic copper and aluminum. The separated metal material contains a small amount of particles including a small amount of metal. After the third crushing, the particle size of the material is broken to less than 2mm. The crushed material is electro-selected to separate the metal from the non-metal. The exhaust gas produced is discharged after cooling, dust collection, and zeolite activated carbon adsorption treatment.

After the above process, the circuit board is divided into tin, ferromagnetic substance, fine powder, metal, and non-metallic particles. The process is fully automated from feeding to the end of the sorting process. The whole set of equipment does not require water, heating, incineration of chemical raw materials, and fire. It is an environmentally friendly recycling project advocated by the state. It replaces the original manual fire, water selection or smelting, etc., cost Low, high efficiency, dry separation at room temperature without any pollution. The metal separation rate reaches about 99%, which is a new process flow for solving pollution.
