Crushing, Sorting Powdering and Shredder Crusher Equipment for Waste Lithium Batteries
Lithium battery mainly consists of shell, positive electrode, negative electrode, electrolyte anddiaphragm.
The positive electrode is formed by coating lithium cobaltate powder on two sides ofan aluminum foil current collector through PVDF which plays a bonding role;The negative electrode structure is similar to the positive electrode and consists of carbon powder bonded toboth sides of the copper foil current collector.
At present, the research on the recycling of wastelithium batteries is mainly focused on the recovery of high-value anode precious metals cobaltand lithium.
Copper in the negative electrode of waste lithium battery (content up to 35%) is animportant production raw material widely used.Carbon powder adhered to it can be used asadditives such as plastics and rubber. Based on the structural characteristics of lithium batteries,our company adopts an environmentally-friendly physical separation process to realize efficientseparation and recovery of waste lithium batteries.
The pretreatment process of waste lithium ion batteries mainly comprises the following steps
| Shredder: | Shredded lithium batteries into smaller pieces. |
| Hammer crusher: | For the secondary crushing of shredded materials. |
| Grinder: | For the grinding of the crushed materials. |
| Separation machine: | Separate the materials after being ground. |
| Collector: | Collect and release the dust . |
| Pulse purifier (air cleaner): | Clean all the dust produced during the operation of the wholesystem. |
| Classifying screen: | Screen the materials sorted by the separation machine,and screen out oflarger metal materials. |
| Magnetic machine: | Separate nickel from the metals. |
| Gravity separator: | Separate those finer materials got from the screening machine and separatethe metal completely. |
| High-pressure blower: | Keep the whole system in a negative state so as to collect the materialsand purity the air . |
1.Lithium battery recycling plant mainly adopts physical recycling method, which has the characteristics of green and low carbon, energy saving and environmental protection, and no secondary pollution.
2.Taking economic and environmental benefits into account, both valuable components can be utilized and harmful components can be treated innocuously.
3.Lithium battery recycling machine was automatic, high recovery efficiency, strong processing capacity, waste lithium battery valuable components recovery rate of more than 98%.
The pretreatment process of lithium battery recycling machine mainly comprises the following steps: after discharging the recovered waste batteries, crushing, magnetic separation, air separation, crushing, gravity separation, screening and other processes are carried out by mechanical equipment.
