The development of new energy vehicles at this stage can be said to be booming, representative of BYD Auto officially announced that since March 2022 to stop the production of fuel cars. This marks the future of the car will be a faster pace into the new energy era, the future of new energy vehicle technology will continue to lead the automotive industry change, lithium battery recycling equipment will continue to help the recycling and reuse of waste lithium battery resources.
The normal use cycle of new energy car battery is generally 5 - 8 years, if it is to run the electric car drip or cab, at most three or four years to be retired, the retired car battery processing is divided into two ways, one is to test the retired lithium battery, the battery after passing the test for secondary use, the other is to test the unqualified products for physical disassembly and reuse.
The following is a description of the new energy vehicle lithium battery recycling processing equipment process.
1. New energy vehicle lithium battery physical disassembly.
First of all, these new energy automotive lithium batteries will be discharged, after the discharge of new energy automotive lithium batteries through the lithium battery recycling equipment conveyor into the heavy-duty battery shredder for forced dismantling, dismantling the battery material into the crusher second crushing process.
2. Magnetically selected steel shell
Lithium battery recycling and processing equipment coarse broken battery materials through the conveyor above the suspended magnetic separator for steel shell sorting separation, separation of steel shell materials through the screw conveyor into the ton pack centralized collection.
3. Sieving machine to collect powder
From the previous step into the large sieving machine for material sieving sorting processing, sieving machine is generally divided into two kinds, one is a linear sieving machine, the other is a drum sieving machine, some in order to replace the screen is convenient to make the octagonal drum sieve, the kind of sieving machine is a matter of opinion, each has its own advantages, right, through the sieving machine sieving, basically recycled 70% of the black powder material contained in the waste battery.
4. Air separation machine air extraction film
The remaining diaphragm and positive and negative pieces into the lithium battery recycling equipment air separation system for the separation of the battery diaphragm and positive and negative copper and aluminum foil air separation. After the separation of the diaphragm for the second powder sieve separation separation.
5. Positive and negative secondary de powder
After the diaphragm air separation machine air separation, the remaining positive and negative flakes for the second de-powdering and crushing, the second de-powdering after the second sieving and powder recycling collection, the positive and negative flakes on the powder material to collect again.
6. Positive and negative copper and aluminum separation
The copper and aluminum particles on the screen surface of the sieving machine enter the airflow sorter equipped with the lithium battery recycling processing equipment, which separates the copper and aluminum particles.
