Technical field

The invention relates to the technical field of battery recycling, specifically a waste recycling and processing device for new energy battery manufacturing.

Background technique

Used batteries and toxic solidified materials are usually mixed into domestic waste. The main treatment methods are sanitary landfill, composting and incineration. Insufficient landfill will pollute water sources and soil, especially batteries containing heavy metals, which can be disposed of through leaching.
