Working Principle Of Li-Battery Recycling Plant

1. The resource utilization of metal copper and carbon powder in the negative material of waste lithium battery can be realized through the combined process of hammer crushing, vibration screening and air separation;

2. The negative material can be effectively peeled off between the carbon powder and the copper foil after being crushed by hammer vibration, and then the copper foil and the carbon powder can be preliminarily separated by vibration sieving based on the difference in size and shape between the particles. The results of hammer vibration peeling and sieving separation show that copper and carbon powder are enriched in the particle size range of particle size greater than 0.250 mm and particle size less than 0.125 mm, respectively, with grades as high as 92.4% and 96.6%, which can be directly sent to downstream enterprises for recycling use;

3. For crushed particles with a particle size of 0.125~0.250 mm and a low copper grade, air separation can be used to achieve effective separation between copper and carbon powder. When the air velocity is 1.00 m/s, a good recovery effect can be obtained.
