The production line of waste lithium battery recycling equipment adopts physical recycling method, supplemented by three waste treatment measures. It has the features of green, low carbon, energy saving, environment protection and no secondary pollution, taking into account the economic and environmental protection benefits. It can not only realize the utilization of valuable components, but also harmlessly treat the harmful components. The whole recycling process is realized with industrial automation, high recycling efficiency and strong processing capacity. The processing capacity is 500 kg per hour, and the annual processing capacity is 5000 tons, and the recycling rate of waste lithium battery reaches more than 90%. After the waste lithium battery is electrified or discharged, a ji shredded and crushed.
After crushing, the material is heated and dried by conveyor during conveying, then the iron shell and diaphragm paper are removed by sorting equipment, then the lithium battery positive and negative pole mixture is left behind, then further fine crushing, electrostatic separation and sieving treatment by fine crusher and water mill ball mill (granulator), so as to separate and recover aluminum, copper and pole plate binder.
The resource utilization of metallic copper and carbon powder in waste lithium battery negative electrode material can be realized by the combination process of hammer vibration crushing, vibration screening and airflow sorting; after hammer vibration crushing, the negative electrode material can effectively achieve mutual stripping between carbon powder and copper foil, and then according to the inter-particle size difference and shape difference vibration screen can initially separate copper foil and carbon powder.
