　　The positive material of lithium battery is lithium cobaltate powder and the negative material is graphite powder, both positive and negative contain a large amount of nickel, copper, aluminum and other metal materials. If the waste or unqualified lithium batteries can be effectively recycled, it can not only reduce the pressure of waste batteries on the environment, but also avoid the waste of cobalt, nickel and other metal resources. The process difference of separating positive and negative pieces of waste lithium battery recycling and treatment equipment.

　　The system includes feeding platform, conveyor, shredder, analyzer, induced draft fan, a collector and two collectors, pulse purifier and grading sieve and sorter; the output of the feeding platform is connected to the conveyor, the output of the conveyor is connected to the shredder, the output of the shredder is connected to the analyzer, the output of the analyzer has two: one output is connected to a collector by the induced draft fan, the second output is connected to the grading sieve and sorter. The output of the analyzer has two outputs: one output is connected to a collector via the induced draft fan, the second output is connected to a grading sieve, the output of a collector is connected to a second collector, the exhaust port of the second collector is connected to a pulse purifier, and the discharge port of the collector is connected to a material collection device; the output of the grading sieve has three outputs: one output is connected to a collecting device via the induced draft fan, and the second and third outputs are connected to a metal processing device. The metal processing device includes airflow sorter and aluminum powder collection device, the second output of the grading sieve is connected to the airflow sorter, the third output of the grading sieve and the metal output of the airflow sorter are connected to the aluminum powder collection device, the non-metal output of the airflow sorter is connected to a collector through the induced draft fan, and the material collection device is lithium cobaltate powder collection device, and the discharge port of the first and second collectors are connected to the lithium cobaltate powder collection device.

　　The waste lithium battery positive material is conveyed to the crusher through the conveyor and crushed to 15-25 mesh; the material crushed by the crusher is conveyed to the analyzer, which separates the crushed material by air separation and sorts out the metal material and lithium cobaltate powder; the sorted lithium cobaltate powder is conveyed to the collecting device through the induced fan for collection, and the exhaust gas in the collecting device is purified through the pulse purifier and output; the metal material analyzed by the analyzer goes to the classifying screen for screening, and the waste gas in the collecting device is purified through the pulse purifier and output; the metal material analyzed by the analyzer goes to the classifying screen for screening. The metal materials analyzed by the analyzer enter the grading sieve for screening, and the grading sieve further separates the metal materials and separates the lithium cobaltate powder and metal parts. The separated lithium cobaltate powder is collected in the collector through the induced draft fan, so that the non-metallic part of lithium cobaltate powder and the metallic part of aluminum powder in the positive piece are separated.

　　Lithium battery recycling processing equipment for negative processing, the specific differences are as follows: the metal processing device includes magnetic separator, specific gravity sorter, copper powder collection device and nickel collection device, the second output of the grading sieve is connected to the specific gravity sorter, the third output of the grading sieve is connected to the magnetic separator, the magnetic separator has two material outputs: one material output is connected to the nickel collection device, the second material output is connected to the copper powder collection device, the specific gravity sorter metal output is connected to the nickel collection device, the second material output is connected to the copper powder collection device, the specific gravity sorter metal output is connected to the nickel collection device. The metal output of the sorting machine is connected to the copper powder collection device, the non-metal output is connected to a collector through the induced draft fan, the said material collection device is a graphite powder collection device, the first and second collector outlet are connected to the graphite powder collection device respectively.

　　Lithium battery recycling processing equipment negative processing process consists of the following processes: the waste lithium battery negative material is conveyed to the crusher through the conveyor, crushed to 15-25 mesh; the crushed material is conveyed to the analyzer, which separates the crushed material into metal material and graphite powder; the separated graphite powder is conveyed to the collector device through the induced fan, and the exhaust gas in the collector device is cleaned through the pulse purifier and then output; the graphite powder collection device is connected to the collector outlet. The metal materials analyzed by the analyzer enter the grading sieve for screening, and the grading sieve further separates the metal materials and separates the graphite powder and the metal part, and the graphite powder output from the grading sieve goes to the collector through the induced draft fan from the first output, and the copper powder screened from the grading sieve goes to the magnetic separator through the output, and the nickel in the copper powder is separated by the magnetic separator, and the other materials screened from the grading sieve go to the collector through the second output. The other materials screened from the grading sieve enter the specific gravity sorter through the second output, which separates the other materials screened from the grading sieve by specific gravity and further separates the copper powder and graphite powder, and the separated graphite powder is collected in the collector through the induced draft fan. So far, the non-metallic part of graphite powder and the metallic part of copper powder and nickel in the negative are separated.
