1.Fully discharged, the discharged waste lithium battery crushes the material to about 10cm by crushing, and then enters the carbonization furnace through the conveyor, the separator is directly carbonized during the carbonization process, the electrolyte can be pyrolyzed and gasified, and the adhesive is gasified. Because the furnace is almost a confined space, the anaerobic conditions are met, so that the diaphragm, adhesive and electrolyte are heated inside the carbonization furnace for pyrolysis and gasification, and the flue gas generated passes through the recovery pipeline and flue gas purification system to achieve the effect of reciprocating circulation heating and hydrolysis.

2.The carbonized material is then screened through the crusher through the wind conveying system into the fully enclosed linear screen for the first screening, and the positive and negative electrode powder is driven to the closed conveyor below through the linear sieve and transported to the ton bag (a finished powder).

3. The remaining diaphragm, copper and aluminum, shell, etc. pass through the belt magnetic separator to separate the iron in the material, and the diaphragm enters the ton bag for collection through the wind extraction equipment.

4. After removing iron, the material enters the grinding machine for grinding, and the ground material particles are about 50-60 mesh, which enters the cyclone aggregate through negative pressure conveying, and then enters the drum screening machine through the discharge. The upper layer of the drum screen is discharged into large particles such as diaphragm and plastic, which can be directly bagged, and the middle layer of materials is conveyed into the specific gravity separator for copper and aluminum separation.

5.The lower material is finished black powder, which can be directly bagged. In addition, the air outlets from the crusher, linear screen, aggregate, copper and aluminum separator are connected with the dust collector for dust removal and odor removal. In this way, the entire set of equipment completes the process required for production. The advantages of this set of equipment are simple structure, less loss parts, high efficiency, high powder yield, low copper and aluminum content of finished materials, and less spilled dust.
