The waste mobile phone lithium battery recycling and processing equipment mainly adopts physical recycling methods, supplemented by "three wastes" disposal measures, and has the characteristics of green low carbon, energy saving and environmental protection, no secondary pollution, etc. It can also be used for harmless treatment of harmful components. The entire recycling process has achieved industrial automation, with high recycling efficiency and strong processing capacity. The processing capacity is 500 kg per hour, and the annual processing capacity reaches 5,000 tons. The recycling rate of valuable components of waste lithium batteries is more than 78/10.

Cobalt, lithium, copper and plastics in waste lithium batteries are valuable resources with high recycling value. Therefore, scientific and effective treatment and disposal 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.

Lithium Battery Recycling Machine

Mobile phone lithium battery equipment process flow:

The waste batteries are sent to the Grade A shredder by the conveyor for shredding. The shredded materials are sent to the secondary multi-knife shredder through the conveyor for primary shredding, and the secondary shredded materials enter the conveyor. At the same time, magnetic separation equipment is set up, which can separate the iron in the material. The sorted materials are sent to the air separator through the conveyor, the separator paper in the positive and negative electrodes is separated by the induced draft fan and the cyclone feeder, and the sorted positive and negative electrodes are sent to the tertiary pulverizer. For fine crushing, crush the material to about 20 mesh. The pulverized material enters into the cyclone separator from the negative pressure system for dust filtration, and is separated by two airflows to separate the materials of different densities into layers, and then separates the positive and negative materials with copper, aluminum, nickel and other materials, And all the ultrafine dust is brought into the pulse dust collector by the negative pressure system for collection. 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 national emission standard before being discharged at high altitude.

Introduction of mobile phone lithium battery crushing equipment;

Cobalt, lithium, copper and plastics in waste mobile phone lithium batteries are valuable resources with high recycling value. Therefore, scientific and effective treatment and disposal 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 positive electrode is formed by coating lithium cobalt oxide powder on both sides of the aluminum foil current collector through PVDF that acts as a bond; the negative electrode structure is similar to the positive electrode, and is composed of carbon powder bonded to both sides of the copper foil current collector. At present, research on the recycling of waste lithium batteries mainly focuses on the recovery of high-value cathode precious metals cobalt and lithium, and there are few reports on the separation and recovery of anode materials. In order to alleviate the increasingly serious problems of resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to realize full-component recycling of waste materials. The copper in the negative electrode of the waste lithium battery (content is about 35%) is an important production raw material widely used, and the carbon powder adhered to it can be used as additives such as plastics and rubbers. Therefore, the effective separation of the negative electrode constituent materials of the waste lithium battery has a driving effect on realizing the resource utilization of the waste lithium battery to the maximum extent and eliminating its corresponding environmental impact. Working principle The raw materials are crushed to less than 10mm by a crusher, and then enter the particle crusher for peeling and crushing, and then enter the micropowder classifier for separation treatment, and the tail ash is collected by the subsequent cyclone separator and pulse dust collector.
