Lithium battery crushing and recycling technology

Time:2021-12-03 10:27 Author:Suny Group

 

SUNY GROUP waste lithium battery recycling and treatment equipment mainly adopts physical recycling methods, supplemented by "three wastes" disposal measures. It has the characteristics of green, low-carbon, energy-saving and environmental protection, and no secondary pollution. It also takes into account economic and environmental benefits, and realizes valuable components. The use of, but also harmless treatment of harmful components. The entire recycling process has been industrially automated, with high recycling efficiency and strong processing capacity, with a processing capacity of 500 kg per hour and an annual processing capacity of 5,000 tons. The recycling rate of valuable components of waste lithium batteries is more than seven or eight.

Lithium Battery recycling plant

Cobalt, lithium, copper and plastics in waste lithium batteries are precious resources and have a high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits.

The scrap lithium battery is sent to the Class A shredder by the conveyor for shredding. The shredded material is sent to the secondary multi-knife crusher through the conveyor for the first crushing, and the material after the second crushing enters the conveyor. At the same time, a magnetic separation device is set up in the machine, which can separate the iron in the material. The sorted materials are sent to the air-flow sorting machine by the conveyor, the separator paper in the positive and negative electrodes is separated by the induced draft fan and the cyclone, and the sorted positive and negative sheets are sent to the three-stage crusher For fine crushing, the material is crushed to about 20 mesh. The pulverized material enters the cyclone separator through the negative pressure system for dust filtration, and passes through two airflow sorting, so that the materials of different densities are layered, and then the positive and negative materials are combined with copper, aluminum, nickel and other materials. And all the ultra-fine dust is brought into the pulse dust collector by the negative pressure system for collection. The filtered tail gas will continue to be sent from the negative pressure system to the tail gas treatment equipment for air purification, so that it can meet the national emission standards before being discharged at high altitude.
