Xinxiang Traceability Environmental Protection Equipment Co., Ltd.
1, through the combination of hammer crushing, vibrating screening and airflow separation technology, can realize the resource utilization of metal copper and toner in waste lithium battery anode materials
2. Negative material can be effectively peeled off between toner and copper foil by hammering and crushing. Copper foil and toner can be initially separated by vibrating screen with size difference and shape difference between particles.The results of hammer stripping and screening separation showed that copper and toner were rich in the range of particle size greater than 0.250mm and particle size less than 0.125mm, respectively, with grade of 92.4% and 96.6%, which could be directly recycled to downstream enterprises
3, For the particle size of 0.125~0.250mm, copper grade low particle, through the airflow separation can realize the effective separation between copper and toner, airflow speed of 1.00m/s can achieve a good recovery effect, copper recovery of 92.3%, grade of 84.4%.
