Separator of different granularities of lithium ion batteries cathode materials

The utility model discloses a separator of different granularities of lithium ion batteries cathode materials, including the agitator tank, material output tube and a plurality of output branch road,each exports the valve that the branch road all was provided with unit collector and control material entering unit collector, each unit collector sets up the end at each output branch road, materialoutput tube end is provided with the second draught fan, still be provided with the controller of control second draught fan wind -force, this is through the setting of each output branch road, cathode material stirs the back in the agitator tank, because the second draught fan produces the negative pressure in the material output tube, and then make cathode material enter into in the material output tube in the agitator tank, the rethread is controlled each valve open and is closed, get into respectively in the unit collector of respectively exporting the branch road with the cathode materialwho isolates different gra
