Recycling and Utilization of Waste Lithium Batteries

At present, the recycling rate of lithium batteries is very low, and a large number of waste lithium batteries are abandoned, which poses a huge threat and pollution to the environment, and is also a waste of resources. 1.8%, copper 8%~10%, aluminum 4%~8%, shell alloy 30%. How to deal with waste lithium batteries, recycling and utilization of waste lithium batteries?

The material is sent to the primary crusher by the conveyor for primary crushing, and the material after primary crushing is sent to the secondary crusher through the conveyor for secondary crushing. The iron in the material can be sorted out. After the iron is removed by the material conveyor and the magnetic separator, it enters the three crusher for fine crushing, and the material is crushed to powder.

The powder state material enters the cyclone separator from the negative pressure system for air filtration, and falls to the air separator through the fan, and is sorted by the air separator, so that the materials of different densities are stratified, and the metal is separated out. , and all non-metals are brought into the pulse dust collector by the negative pressure system for concentration. The filtered exhaust gas will continue to be sent to the exhaust gas treatment equipment by the negative pressure system for air purification, so that it can meet the emission standard and then be discharged at high altitude.

The separation in the lithium battery recycling equipment consists of magnetic separation, air separation, etc. Magnetic separation can separate the ferromagnetic material in the crushed material; air separation can divide the powder in the crushed material and the lighter plastic diaphragm into equal parts At the same time, part of the volatile electrolyte adhering to the material is extracted with the wind; the pretreatment and recycling of waste lithium-ion batteries is mainly to recycle waste lithium batteries, after discharging, use mechanical equipment for crushing, air selection, crushing, Gravity sorting, sieving and other processes can effectively separate the active materials on the positive and negative pole pieces from the copper and aluminum foils.
