Compared with the variety of lithium-ion batteries, the available treatment methods for waste lithium-ion batteries are very limited. At present, various treatment methods for waste lithium-ion batteries have their own problems, and the method of disassembling batteries and refining precious metals is still the best way to give consideration to environmental protection and economic benefits. Compared with other valuable metals such as copper and aluminum in discarded lithium-ion batteries, there may be a serious shortage of lithium resources in the future. Recycling lithium salt from discarded lithium-ion batteries has also become a hot topic for some industry insiders.

It is understood that the intermediate products recovered from waste lithium-ion batteries have high requirements on consistency. The recycled materials must come from the same lithium-ion battery. At least, the positive and negative electrode materials and electrolyte of the lithium-ion battery are consistent, so that they can be reused in new batteries. The automatic cycle process of waste lithium ion battery recycling equipment technology becomes the key.

Safe and efficient production line of lithium ion battery crushing and recycling equipment, its production line process enters the shredder for shredding through discarded batteries, and the shredded batteries enter the special crusher for crushing, breaking up the positive and negative pole pieces and separator paper inside the batteries. The broken materials enter the collector through the induced draft fan, and then the dust in the crushing process is collected and purified through the pulse dust remover. The materials entering the collector enter the air flow separation screen through the air shutter, The diaphragm paper in the positive and negative electrode sheets is collected by air flow plus vibration, and the dust produced by the air separator is collected at the same time. Then the mixture is separated and recycled by a combined process of hammer crushing, vibration screening and air separation.

The lithium ion battery recycling equipment separates the aluminum, copper and positive and negative electrode materials in the discarded positive and negative electrode sheets for recycling purposes. The whole production line operates under negative pressure, and there is no dust overflow during the production process. The production environment is cleaner and more environmentally friendly, and the dust emission concentration meets the environmental requirements. The crushing equipment can scientifically and effectively treat and dispose the waste lithium ion battery, which has not only significant environmental benefits, but also good economic benefits.
