Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery crushing equipment, in particular to a battery material indiscriminate crushing system. Background Art

[0002] At present, there are many types of scrapped lithium battery materials, which differ in appearance, materials, etc. For enterprises that recycle ternary lithium batteries, polymer lithium batteries, or mixed cathode plates, soft-pack batteries and shell batteries (such as scrapped batteries or blade batteries for new energy vehicles), it is generally necessary to distinguish the corresponding materials and then use the corresponding equipment for physical disassembly.

[0003] For raw materials with larger dimensions, using a double-shaft shredder can significantly improve processing efficiency. For materials with smaller dimensions (taking 18650 cylindrical batteries as an example), double-shaft shredders are prone to problems such as missed cutting and incomplete disassembly. In this case, using a single-shaft shredder for disassembly can significantly improve recycling capacity.

[0004] If both double-shaft and single-shaft crushing production lines are set up at the same time, it will not only occupy more space and increase production costs sharply, but it will also be difficult to increase the equipment utilization rate of each line at the same time.
