Lithium battery is composed of battery shell, positive electrode, negative electrode, lithium battery electrolyte and diaphragm. The positive electrode is composed of lithium cobaltate powder glued to the two ends of aluminum platinum collector liquid based on PVDF, which is effective in bonding; the structure of the negative stage is similar to that of the positive stage, which is composed of carbon powder bonded to the two ends of copper po collector liquid. At the present stage, the key scientific research on the regeneration of waste lithium battery resources is concentrated on the purchase of precious metals cobalt and lithium with high value. The copper in the negative level of waste lithium batteries (35% or more) is a key production material used throughout the world, and the carbon powder adhered to it can be used as an additive for plastics and vulcanized rubber. Therefore, the negative level of waste lithium batteries constitute the original material to develop a reasonable separation out, to complete the degree of waste lithium battery resource regeneration, there will also be the effect of environmental hazards. Waste lithium battery recycling machinery can recover what metal materials?
Waste lithium batteries sent by the conveyor into the twin-shaft shredder for shredding, shredding the material according to the conveyor sent into the secondary multi-blade shredder to carry out secondary crushing, secondary crushing of the material into the conveyor in addition to set the beneficiation equipment, can be sorted out the iron in the material. The sorted materials are sent to the cyclone sorter by the conveyor.
According to the centrifugal fan and hurricane under the feeder to extract the diaphragm paper in the positive and negative pieces, the sorted positive and negative pieces into the three-stage crusher to start the crushing, the material will be crushed to 20 mesh up and down. The crushed materials are fed into the cyclone dust collector by the negative pressure system to start the soot filtration.
According to the secondary cyclone sorting, so that the different relative density of chemical substances to develop levels, and then obtain the positive battery positive material and copper, aluminum, nickel and other raw materials, and all the ultra-fine dust from the negative pressure system to the bag filter to develop the collection. The exhaust gas obtained by filtration will be sent again by the negative pressure system to the exhaust gas treatment machinery and equipment to develop air filtration, so that it can be standardized and then discharged at high altitude.
Lithium battery recovery processing machinery for waste lithium battery positive and negative pieces of aluminum platinum, copper and positive battery positive electrode material to separate out the processing, to facilitate the purpose of recycling. All production lines negative pressure operation, the production process of dust outflow, the working environment is cleaner and environmental protection, soot emission concentration value to achieve the relevant provisions. The shredding machinery on the waste lithium battery to carry out scientific separation research, reasonable processing and sorting, not only has obvious ecological benefits, but also has excellent economic benefits.
