The equipment is characterized by a high level of mechanical automation, but the working process is complicated and the equipment is also very expensive; and modern lead-acid batteries adopt the valve-controlled maintenance-free technology of AGM separators, and most of the failed waste batteries have dried up internal fluid, and the acid cannot be poured It will affect the sorting effect after crushing.

Patent No. CN200780047761.0 also discloses a crushing and sorting method for waste lead-acid batteries. The batteries are first structurally crushed by a punching machine, and then put into an alligator crusher for secondary crushing. This method adopts double crushing, the process is complicated, and there are too many equipments, so it is still not an optimal solution.

Modern maintenance-free batteries generally use ABS plastic shells and stronger structures, and their strength and toughness are higher than those of the original open-type batteries. Crushing waste batteries to the required particle size increases operating costs and affects work efficiency and results.
