(2) shearing and crushing the waste lithium ion battery, so that the metal shell, diaphragm and positive and negative plates of the battery are fully dispersed without wrapping;
(3) The crushed lithium battery is sent to a crusher by a conveyor, and the metal shell is crushed into small particles;
(4) the ground lithium battery material passes through a disc screen, and the powder collection work is also carried out synchronously in this process;
And (5) separating the copper foil and the aluminum foil after recovering the polar powder by a color separation process to obtain high-purity copper foil and aluminum foil.
; (7) negative pressure operation in the whole process;
(8) Dust generated in the production process is treated by pulse dust collector to meet the requirements of EIA.
