Mobile phone lithium battery recycling and processing 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 the use of valuable components. , But also harmless treatment of harmful components. The entire recycling process has realized industrial automation, with high recycling efficiency and strong processing capacity, with an hourly processing capacity of 500 kg, an annual processing capacity of 5,000 tons, and a recycling rate of more than 90% of valuable components of waste lithium batteries.
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. Lithium batteries are mainly composed of shell, positive electrode, negative electrode, electrolyte and separator.
The waste batteries are sent by the conveyor to the Class A shredder for shredding. The shredded materials are sent to the secondary multi-blade crusher through the conveyor for secondary crushing, and the secondary crushed materials enter the conveyor. At the same time, a magnetic separation device is set up to separate the iron in the material. The separated material is sent to the air separator through the conveyor, and the diaphragm paper in the positive and negative electrodes is separated by the induced draft fan and the cyclone. The sorted positive and negative plates are put into a three-stage pulverizer for fine crushing, and the materials are 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 to separate the materials of different densities, and then obtain the positive and negative materials and 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 exhaust will continue to be sent from the negative pressure system to the exhaust treatment equipment for air purification, so that it will meet the national emission standards before being discharged at high altitude.
